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:
False
Explanation:
Convergence of plates can occur when
two geological tectonic plates are moving towards each other, where one of this plate go in direction beneath the other plate. As they moved towards each other mountain chain can be formed in a situation whereby the two plates has the same density.
Hence, the best option is FALSE because it is in only "DIVERGENCE PROCESS " that the plates moves away from each other.
Answer: Antibiotics targets the synthesis of protein, nucleic acid, folate and cell wall.
1. Synthesis of protein; antibiotics binds to either 30s or 50s ribosomal subunits blocking the polypeptide from the exiting the tunnel thus inhibiting a full completion of protein expression or production.
2. Nucleic acid synthesis; Antibiotics also act by inhibiting genetic expression, DNA transcription and replication where DNA makes exact copies of itself, as well as RNA molecules preventing bacterial growth.
3. Cell wall synthesis; Inhibition of cell wall synthesis in microorganisms will prevent it from replication and growth.
4. Folate synthesis; Folic acid also known as vitamin B9 helps in DNA replication and cell division. Folate antagonists such as aminopterin kills bacteria by preventing folic acid production required for DNA replication.
Answer:
it is similar because it involves multiple body parts.
it is different because it doesn't involve breaking down anything or providing things through the blood.
