When the gene encoding a certain cytoskeleton protein is deleted, the resulting mutant cells round up and do not form their normal appendages. These mutants can be rescued when a gene encoding an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, but not when a gene encoding a C-terminal GFP fusion is expressed. Which fusion protein is appropriate to use in studying cellular localization and activity

Answers

Answer 1

Answer: N-terminal green fluorescent protein (GFP)

Explanation:

Protein synthesis takes place in ribosomes located in the cell cytoplasm, in which amino acids are transported by transfer RNA corresponding to each amino acid to the messenger RNA where they bind in the appropriate position to form new proteins. The messenger RNA has a sequence of nucleotides that are translated into protein, as each codon (set of three amino acids) codes for one amino acid.

Genes are the storage units of genetic information, so they are segments of DNA that contain the information on how the cells of the organism should function. Each gene codes for a protein, so if a gene is damaged or absent, the protein will not be obtained. In this case, mutant cells with a deleted gene, will round up and wont form their normal appendages. This mutation can be rescued or repaired with a gene that encodes an N-terminal green fluorescent protein (GFP) fusion of the protein. The N-terminal end is the amino-terminal end and it refers to the end of a protein that ends with an amino acid that has a free amino group. The C-terminus or carboxyl-terminus is the end of a protein that ends in a carboxyl group. The convention for writing peptides is to place the C-terminal end to the right and write the sequence from the N- to the C-terminal end. So, when an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, the gene will produce the protein with a GFP tag.

GFP is Green Fluorescent Protein, and it is a protein produced by the jellyfish Aequorea victoria that emits bioluminescence in the green region of the visible spectrum. When a gene is fused to another gene (at either the N- or C-terminus, although in this case it is the N-terminus), the entire messenger RNA is translated together as if it were a single fused protein. Thereby, since the protein will be produce with a GFP tag, it can be seen under the microscope and it will be apropiate to use in studying cellular localization and activity.

There are some considerations that this problem does not question, such as that there must be a start codon for protein synthesis and a stop codon, and this stop codon must not be in the middle of the gene or between the gene and the GFP tag.

Answers

Answer:

bioaccumulation of chemicals is the problem concerning all living organisms. This is the result of dynamic equilibrium between the uptake and elimination. The extent to which bioaccumulation occurs determines the toxic effects which are manifested. In some cases, the mechanisms of protection from certain undesirable substances deposited in special sites, to prevent their participation in the metabolic reactions, have evolved. The knowledge on bioaccumulation enables to assess the risk related with the presence of various chemicals in the environment, food, and at workplace and to present quantitatively the ability to control the use and emissions of chemicals.

Plants and certain microorganisms use photosynthesis to create compounds such as carbohydrates. It's an endothermic (heat-inducing) chemical reaction that converts carbon dioxide to sugars using sunlight. Sugars are used by the cell as an energy source as well as a building block for other molecules. Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

4) What factors influence the circulation of the Earth's atmosphere,
thereby producing our weather?

Answers

The movement of air through Earth's -- or any planet's -- atmosphere is called wind, and the main cause of Earth's winds is uneven heating by the sun. This uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure

The uneven heating of the earth's surface is one of the main variables affecting the circulation of the atmosphere globally along with  seasonal variations in precipitation and temperature and Earth turning on its axis.

What is weather?

The state of the atmosphere is referred to as the weather, and can be described in a number of different ways, including the degree to which it is hot or cold, wet or dry, quiet or stormy, clear or cloudy. The troposphere, the lowest layer of the Earth's atmosphere, is where the majority of meteorological events take place. The stratosphere is the next layer up from the troposphere. The term "weather" is used to describe the temperature, precipitation, and other characteristics of the atmosphere on a day-to-day basis.

Variations in air pressure, temperature, and moisture from one location to another are the primary contributors to a day's weather. These disparities can be attributed to the fact that the angle at which the Sun is positioned at any given location varies with latitude. The vast temperature difference between the polar and tropical air masses is what gives rise to the biggest scale atmospheric circulations.

O.  Some species of conifer require fire before fertilization of their seeds can take place.

Explanation:

The true statements regarding conifers and forests include the following:

Most conifer seeds can survive subzero temperatures but will be destroyed by very high temperatures- Most conifers when exposed to heat become destroyed as their viability becomes greatly reduced but can survive very low temperatures as it doesn't affect their viability.

Reforestation of a conifer forest after a wildfire can take many decades because new conifer seeds have to be brought from other areas by animals or wind- This is true as most conifers method of dispersal are through wind, animals, water etc.

Some species of conifer require fire before fertilization of their seeds can take place-  Species such as Lodgepole pine and Banksia require fire for fertilization as their cones or fruits that are completely sealed with resin.

Indicate whether the given structure is located in the outer, middle, or inner ear. pharngotympanic tube helicotrema stapedius

Answers

Answer:

The pharngotympanic tube is in the middle ear.The helicotrema is in the inner ear.The stapedius is in the middle ear.

Explanation:

The ear has three main parts, the outer part, the middle part, and the inner part. The outer part of the ear starts in the auricle, then it continues with the auditory canal, and it finishes with the eardrum. Then we have the middle ear that is separated from the outer one with the eardrum. In this section, it is the pharngotympanic tube, also known as the Eustachian tube. It is a tube that connects the inner ear with the pharynx to regulate internal pressure.

The inner ear has the bony labyrinth and the membranous labyrinth. In this part of the ear, the mechanical signals are transformed into electrical signals. The bony labyrinth has the cochlea, the vestibule, and the semicircular canals. The helicotrema is in the cochlea, and it connects the tympanic duct with the vestibular duct.

The stapedius is a muscle located in the middle ear. Its insertion is in the stapes, a small bone that moves with the vibrations that come from the eardrum to the malleus and the stapes. The stapedius' function is to protect our hearing by reducing the vibrations that enter this part of the ear.
