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: Direct proportion. The salinity of water in the ocean rises with higher temperature because water is evaporated from the ocean, leaving more solutes (salts) in it.
i hope this helps you if it does please mark brain list i really need it to level up :)
Answer:
A. Atmosphere
Explanation:
Atmosphere would be most immediately affected by a decrease in sunlight because sunlight is responsible for the photosynthesis in plants. if sunlight decreases, the photosynthesis reaction is also decreases in plants and less carbondioxide gas is used by the plant from atmosphere for making their food so we can say that atmosphere is greatly affected by the decrease in sunlight.
Answer: The answer is the rental system.
Explanation: It produces, stores and eliminates urine and the fluid waste excreted by the kidneys.
It is an organic catalyst. It speeds up certain chemical reactions in the body.
