Archaea I think this is the right choice
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.
Diffusion is the movement of substances from high to low concentration
osmosis is the diffusion of water through a semipermeable membrane from high to low water concentration
Answer:
The answer is A ( No, the water looks clear but it may contain harmful bacteria or high levels of harmful chemicals in the water.)
