What holds amino acid chains within a protein in shape?​

Answers

Answer:

Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they serve as the catalysts for virtually every biochemical reaction that occurs in living things. This incredible array of functions derives from a startlingly simple code that specifies a hugely diverse set of structures.

In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by different bonds and folded into a variety of three-dimensional structures. The folded shape, or conformation, depends directly on the linear amino acid sequence of the protein.

Cell Definition

“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”

Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.  

Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular structures called cell organelles are suspended in the cytoplasm.

Types of Cells.Prokaryotic Cells

Prokaryotic cells have no nucleus. Instead, some prokaryotes such as bacteria have a region within the cell where the genetic material is freely suspended. This region is called the nucleoid.

They all are single-celled microorganisms. Examples include archaea, bacteria, and cyanobacteria.

The cell size ranges from 0.1 to 0.5 µm in diameter.

the hereditary material can either be DNA or RNA.

Prokaryotes reproduce by binary fission, a form of sexual reproduction.

Eukaryotic Cells

Eukaryotic cells are characterised by a true nucleus.

The size of the cells ranges between 10–100 µm in diameter.

This broad category involves plants, fungi, protozoans, and animals.

The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cells. It is also responsible for cell to cell communication.

They reproduce sexually as well as asexually.

There are some contrasting features between plant and animal cells. For eg., the plant cell contains chloroplast, central vacuoles, and other plastids, whereas the animal cells do not.

Functions of Cell:Provides Support and StructureFacilitate Growth MitosisAllows Transport of SubstancesEnergy ProductionAids in ReproductionCell Membrane The cell membrane supports and protects the cell. It controls the movement of substances in and out of the cells. It separates the cell from the external environment. The cell membrane is present in all the cells. The cell membrane is the outer covering of a cell within which all other organelles, such as the cytoplasm and nucleus, are enclosed. It is also referred to as the plasma membrane. By structure, it is a porous membrane (with pores) which permit the movement of selective substances in and out of the cell.  Besides this, the cell membrane also protects the cellular component from damage and leakage. It forms the wall-like structure between two cells as well as between the cell and its surroundings. Plants are immobile, so their cell structures are well-adapted to protect them from external factors. The cell wall helps to reinforce this function.What is Osmosis?

Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.

Any solvent can undergo the process of osmosis including gases and supercritical liquids.

Osmotic Solutions There are three different types of solutions:

An isotonic solution: is one that has the same concentration of solutes both inside and outside the cell.

A hypertonic solution: is one that has a higher solute concentration outside the cell than inside.

A hypotonic solution; is the one that has a higher solute concentration inside the cell than outside.

Effect of Osmosis on Cells

Osmosis affects the cells differently. An animal cell will lyse when placed in a hypotonic solution compared to a plant cell. The plant cell has thick walls and requires more water. The cells will not burst when placed in a hypotonic solution. In fact, a hypotonic solution is ideal for a plant cell.

An animal cell survives only in an isotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop.

The osmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute. The minimum pressure required to stop the solvent transfer is called the osmotic pressure

Significance of Osmosis Osmosis influences the transport of nutrients and the release of metabolic waste products.It is responsible for the absorption of water from the soil and conducting it to the upper parts of the plant through the xylem. It stabilizes the internal environment of a living organism by maintaining the balance between water and intercellular fluid levels. It maintains the turgidity of cells. It is a process by which plants maintain their water content despite the constant water loss due to transpiration. This process controls the cell to cell diffusion of water. Osmosis induces cell turgor which regulates the movement of plants and plant parts. Osmosis also controls the dehiscence of fruits and sporangia. Higher osmotic pressure protects the plants against drought injury.

Answers

Answer:

the correct answer is B Frame shift insertion

Explanation:

plz give me brainiest

Frameshift-insertion mutations affect the amino acid sequences.

Thus, The insertion or deletion of nucleotide bases in amounts that are not multiples of three is referred to as a frameshift mutation in a gene.

This is significant because a cell reads the genetic code for proteins in groups of three nucleotides.

These so-called "triplet codons" each stand for one of the 20 different amino acids that go into making a protein. This normal reading frame will be disrupted by a mutation, which will result in an inaccurate reading of the entire gene sequence after the mutation.

Thus, Frameshift-insertion mutations affect the amino acid sequences.

Answers

The answer is A it can be reused.

The monomer can be reused once the polymer is deconstructed. So, the correct option is (A).

What is Monomer?

A monomer is defined as a molecule which can react with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization.

These are described as atoms or small molecules which bond together to form more complex structures known as polymers. There are four main types of monomer which include sugars, amino acids, fatty acids, and nucleotides.

Monomers can also be reused again when the polymer is deconstructed.

An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings were germinated on moist paper towels at 20ºC for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD+. Predict the most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction.

Answers

Answer:

The definition is listed in the clarification segment below, and according to the present circumstances.

Explanation:

It undergoes different morphological as well as biochemical modifications mostly during germination. Product contains nutrients and even some hydrolases such as energy, carbohydrates. Owing to the availability of phytic compounds, the seed coat seems to be very durable in nature. Hydrolytic enzymes launch their function by consuming oxygen throughout order to remove this hard coating. In several other processes, including the electron transport system as well as the Kreb process, oxygen also becomes necessary.

The initial phase of germinating seeds requires anaerobic environments where even the enzymes dehydrogenase can function. The subsequent dehydrogenase enzyme brings the electron throughout the electron transport system from either the base to oxygen.  Unless the oxygen frequency is compared with varieties A and B, it can be seen through the analysis that variety B actually absorbed more oxygen. Oxygen intake rates are also depending upon period.The impact of temperature mostly on absorption of oxygen seems to be present. Shift the supply at low temperatures have a low intake of oxygen, while varieties grown over extreme temperatures use much more oxygen. The metabolism of such a seedling is influenced by temperature. Metabolically active young plants display a larger intake of oxygen.

New Zealand has a population of 4,326,380 and has an area of 103,736 miles squared while Australia has an area of 2,967,909 miles squared and a population of 21,905,140. Explain how New Zealand can have a larger population density than Australia even though it has a smaller total population.

Answers

The reason they have a higher population density is because they have more people on average in a certain area, because New Zealand is smaller they are given less space to live, this means that more people are crammed together, making the density of people within a square mile higher. When you give less square miles, you reduce the amount you have to divide the population by, which makes the density go up.

( In case you wanted the calculations for the density on New Zealand and Australia, it is about 41 to 42 people a square mile in Zealand, and maybe 7 or 8 per square mile in Australia.)

Explain at least three ways in which a mutation in an individual's DNA could occur, and describe at least 2 effects a mutation could have on an individual's traits.

Answers

Answer:

Explanation:

Three ways in which mutation could occur are

1) If an error occurs during DNA replication and it's not corrected in time by DNA polymerase.

2) If there is a deletion of a base(s) in the sequence of the DNA. The deletion of a DNA nucleotide/base could also cause a mutation as that could affect the formation of an enzyme or protein useful in building and/processing certain body parts/processes.

3) Thymine dimerization: Thymine dimers are mutations that prevent DNA from replication or even transcription hence preventing a cell from undergoing division (hence causes cancer). They are formed when covalent bonds are formed between the bases of a DNA sequence (somewhere around the carbon-carbon double bond).

The two effects are

1) It could cause cancer as described in (3) above (in the case of thymine dimer)

2) It could lead to deformity in an individual because of the gene that is supposed to code for the last finger has a base deletion, that could eventually lead to the absence of that finger or a shorter or "strange" finger.

Explanation:

Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. During the initiation of cell differentiation, transcription factors activate only  the genes to be expressed. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, and the presence of mutagens(factors that cause mutation).

Differentiation occurs in zygotes numerous times resulting in the formation of a fully developed organism. Also in unspecialized cells known as stem cells, differentiation occurs leading to the formation of various cells of the organs and tissues of the body.

2. Meiosis is a type of cell division in which gametes or sex cells are produced. A single cell divides twice producing daughter cells with half the number of chromosomes present in the parent cell. In humans, the chromosome number is 46. After, meiosis, the haploid number of chromosomes produced is 23.
