Answer:
double helix, which is made up of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).
Explanation:
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:
Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide. Or, place carbon dioxide gas in limewater, and if it turns milky and gets chunks, it is carbon dioxide.
On the islands of the Galapagos lives a group of birds called finches. There are 13 species in this group. These species have diverse ecologies--some eat seeds, some eat insects, some eat fruit, and some even eat cactus. Although the bodies of these species look fairly similar, their beaks are very different. That is because it is their beak that is adapted to these diverse ways of feeding (Figure 8.14).
