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.

Answer:
15
Explanation:
According to linkage theory, two genes present on the same chromosome tend to get inherited together. So the gametes produced are not equal in number and parental type offspring are observed more in number than the new recombinant types.
Here, normal wings, red eyes (420) and vestigial wings, purple eyes (430) are most in number hence they are the parental type offspring.
Vestigial wings, red eyes = 80 : recombinant
Normal wings, purple eyes = 70 : recombinant
Distance between two genes in cM = recombination frequency = (total number of recombinants / total progeny)*100
= [(80+70)/(420+80+70+430)]*100
= (150/1000)*100
= 0.15*100 = 15cM
