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:
D, the offspring inherit a wider variety of genetic info
Answer:
The size is reduced as 80-95% of the available energy at one trophic level is not transferred to the next
Explanation:
There is loss of energy as it is transferred between trophic levels. The decrease in energy as it moves up the pyramid is due to energy loss as metabolic heat when one organism is consumed by another from the next level as it moves up the trophic levels.
<h3><u>Answer;</u></h3>
The bacteria require less energy to make offspring,
They do not need a partner
Also the reproduction is faster and rapid compared to sexual reproduction.
<h3><u>Explanation</u>;</h3>
- Asexual reproduction is a type of reproduction that involves one parent and produces offspring that are genetically identical to each other and to the parent.
- In sexual reproduction, on the other hand, two parents are involved, who produce reproductive cells called gametes that unite to form an offspring.
- <em><u>E. coli is a bacteria that reproduces asexually. An asexual reproducing organism can produce many offspring in a short period of time without utilizing energy to find a mate</u></em><u>. </u>
