Answer:
<u>Option-(C,A):</u>Archaea must undergo meiosis prior to cell division, and Each chromosome in a polyploid organism has distinct genetic information.
Explanation:
- <u> Archaea are polyploid:</u>
Archea are prehistoric organisms who can be also termed as the prokaryotic living cells, as they developed from a less developed form to a more complex shape or system. As the feature of being a polyploid makes it easy for any archea to survive in the most severe conditions. As the polyploids contain a number of genetic materials in pair, as each pair is very distinctive in features or more independent in regulating a function then the other. Giving it a more diversity of genetic sequence its genome.
Along, with that the process of meiosis occurs prior to the process or event of cell division. Which is for production of the copies of the parent cell, which posses the same genetic material as that of the parent cells.
Much of the water vapor and carbon dioxide in earth’s atmosphere is found in the troposphere.

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).
