What is the difference between plasma membrane and cell membrane?

Biology

The plasma membrane is the boundary between the cell and its environment. It regulates what enters and exits the cell. Cells must maintain an appropriate amount of molecules to function inside them. They must also have a way to keep things out or to allow things to enter. This is the job of the plasma membrane. The plasma membrane is like the guard at a gated community. The guard must inspect those who enter and those who leave to make sure that only the people and things needed in the community are there.

The cell membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane also serves to help support the cell and help maintain its shape.

The Various kinases can be activated by breaks in DNA.
Sonbull [250]

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).

e) Is this is a silent mutation or a missense mutation? Explain. Hint: Silent mutations have no effect on the amino acid. I RLY
almond37 [142]

Answer:

hope it helped u

plzzz mark as brainliest.

Explanation:

Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation.

Mutations that cause the altered codon to produce an amino acid with similar functionality (e.g. a mutation producing leucine instead of isoleucine) are often classified as silent; if the properties of the amino acid are conserved, this mutation does not usually significantly affect protein function.
