Answer:
The Various Kinases that is activated after the breaks in DNA is after the activation of ATM serine threonine kinase which helps in phosphorylation of other DNA replication check proteins, p53 protein (tumor suppressor protein) etc.
Explanation:
ATM activated by MRN complex at the site of DNA double stranded breaks by phosphorylation. MRN complex activity on ATM induces a conformational change in ATM kinase. So it can bind to its various substrate molecules that helps in DNA replication cycle arrest.
ATM phosphorylates CHK2 protein a product of CHEK2 gene, also known as effector kinases that phosphorylates and helps in deactivation of cyclin dependent kinases (CDKs) that helps in the prevention of progression of mitotic phase.
ATM also phosphorylates the inhibitors of p53 proteins which leads to the overexpression of p21, an inhibitor of (CDKs).
Answer: silence point
A silent point mutation may be an effect of a base-pair substitution (substitution of one base pair with another in DNA). However, silent point mutations are a special case where no amino acids are affected. As a result, since the monomers of proteins are amino acids, there is no change to the sequence of a protein.
I believe the example of an environmental variation in the above question is, A. Marge dyes her hair blue. Variation represents any difference between cells, individual organisms, or groups of organisms of any species caused by either genetic differences or by the effect of environmental factors. Environmental variation is the ability of an organism to alter its phenotype depending on environmental conditions.
