Explain how chromosome behavior during meiosis ensures transfer of parental traits to offspring
gizmo_the_mogwai [7]

Explanation:

During meiosis, sister chromosomes of a homologous pair separate into different cells during gamete formation . This mainly occurs in Metaphase I of meiosis where the homologous chromosomes line up the metaphase plate in their sets. Each chromosomes of a pair are then pulled to different poles of the cells separating them. Each of these chromosomes carries a set of alleles of a gene. Each cell/gamete, therefore, carried half the set of alleles of all genes compared to autosomal cells. There many combinations of these sets that can occur depending on the number of chromosomes the organism has.

These cells when combined with that of another parent during fertilization, form a zygote that grows and develops into a mature organism. The offspring will bear the characteristics of both parents because it inherits half a set of chromosomes from both parents.

Which pathway is affected by an inherited mutation in the atm gene?
Katena32 [7]

The question is incomplete as it does not have the options which are:

photoreactivation

reactivation repair pathway

nucleotide excision repair pathway

UV repair pathway

p53 repair pathway

Answer:

p53 repair pathway

Explanation:

ATM gene or ataxia telangiectasia-mutated is a gene which codes for the protein kinase involved in the DNA double-stranded break.

The DNA double-stranded break is repaired easily as the protein kinase is recruited to the site of the break where it allows the DNA repair machinery to repair the DNA.

The gene also controls the cell growth therefore this gene is important to study cancer.  Since the p53 protein is a suppressor protein which if mutated is repaired by the ATM gene and if the gene becomes mutated then the p53 repair pathway is affected.

Thus, p53 repair pathway is the correct answer.
