DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.
DNA contains genetic information that is passed from adult organisms to their offspring during reproduction.Each offspring forms by the combination of the parent's gene or DNAThe actual sequence of DNA on each of the chromosomes is unique due in part to recombination.recombination causes genetic variation and made everyone unique.This is incorporated in the nucleotide sequences in DNA molecules.Thus, DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA

Question 10
The part of the hemoglobin molecule that combines with oxygen is the heme.
O True
False
Is it true or false
Answers
Answer:
Its true!!Explanation:
Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!

DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymerases seems to be quite limited. However, like DNA mutation, an RNA polymerase error in transcription can cause production of a mutated protein. The limited error correction of RNA polymerase seems to be inconsistent with the potential serious consequence of producing a protein with an altered amino acid sequence. Select three reasons that explain why error correction is not as necessary in RNA polymerases as it is in DNA polymerases.
Answers
The given question is incomplete as the option are not provided however, the correct options are as follows:
Defective proteins are often degraded quickly, making their effects temporary.
Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.
Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.
Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.
ch mRNA molecule is only translated once and then degraded
Answer:
The correct answer is - statements 1, 3, and 4.
Explanation:
DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.
RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited
The process of transcription is quick.

Explain the role of certain plant cells in flood control
Answers
Answer:
To absorb water to lowers the intensity of flood.
Explanation:
The main role of certain plant cells in flood control is to absorb water as well as the decrease the flow of water which slower down the intensity of flood. There are some plants in which their cells absorb huge amount of water which decreases the amount of water in the flood and as a result flood water decreases so that's why vegetation is very important in order to avoid flooded condition.
In a normal cellular protein, where would you expect to find a hydrophobic amino acid like valine?
A.In the interior of the folded protein, away from water.
B.On the exterior surface of the protein, interacting with water.
C.In the transmembrane portion interacting with lipid fatty acid chains.
D.In the interior of the folded protein, away from water, or in a transmembrane portion interacting with lipid fatty acid chains.
E. Anywhere in the protein, with equal probability.
Answers
Answer:
D. In the interior of the folded protein, away from water, or in a transmembrane portion interacting with lipid fatty acid chains.
In a normal protein, it is expected to find valine in the interior of the folded protein, away from water, or in a transmembrane portion, interacting with lipid fatty acid chains (Option D).
Aminoacids can contain hydrophilic side chains that interact with water molecules or hydrophobic side chains that cannot make hydrogen bonds and therefore do not interact with water.
In membrane protein, hydrophilic amino acids are arranged so they can interact with water on the surface of the cell membrane,
Moreover, hydrophobic amino acids of membrane proteins are arranged away from water so they can interact with fatty acid chains in the transmembrane portion of transmembrane proteins or with other hydrophobic amino acids in the interior of the folded protein.
In conclusion, in a normal protein, it is expected to find valine in the interior of the folded protein, away from water, or in a transmembrane portion, interacting with lipid fatty acid chains (Option D).

Answer:
The correct answer is b. an operational definition.
Explanation:
An operational definition constitutes the set of procedures that describe the activities that an observer must carry out to receive sensory impressions, which indicate the existence of a theoretical concept to a greater or lesser degree. In this sense, it tries to clearly indicate how the variables are going to be manipulated or measured and also indicates that to measure a variable, it is necessary to carry out a series of activities or procedures. It is the one that builds or adapts from others, based on the observable characteristics of the phenomenon; indicating the concrete, empirical elements or indicators of the fact to be investigated.

What happens after activation of T cells
Answers
Answer:
Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
Explanation:
Helper T cells become activated when they are presented with peptide antigens by MHC class II molecules, which are expressed on the surface of antigen-presenting cells (APCs). Once activated, they divide rapidly and secrete cytokines that regulate or assist the immune response.
Complete the flowchart to show the stages of cellular respiration and fermentation.
Cellular Respiration and Fermentation
Answers
Answer:
The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.
The fermentation stages are: glycolysis and pyruvate regeneration.
Explanation:
Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.
Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.

Answers
Answer:
Remember that males have an x and y chromosome, while women have two x chromosomes.
Explanation:
This means that a female offspring (daughter) inherits her father's only x chromosome and one of her mother's x chromosomes, while a male will receive his father's y chromosome and one of his mother's x chromosomes.
This means that the boy will necessarily inherit his dad's Y chromosome, and any diseases that it carries.
The chance of a male offspring inheriting the disease is
A) 100%
Answer:
Mother
Explanation:
This mutation needs two X chromosomes. Only the mother has two X chromosomes (XX). The father is male, so he only had one X chromosome (XY).
