r-ruslan [8.4K]

Answer:

d) A constitutively active mutant form of PKA in skeletal muscle cells would lead to an excess in the amount of glycogen available.

Explanation:

This occurs in the process of Glycogenolysis. The process involves breaking down of glycogen to glucose  -1- phosphate and glycogen which helps in the release of glucose into the blood stream to prevent hypoglycemia(low blood sugar). The glucose-1-phosphate is later converted to glucose -6-phosphate. The latter enters the glycolytic pathway in which the reaction is catalysed by the enzyme phosphoglucomutase.

This homeostatic glucose regulation  is regulated by the protein kinase(PKA)/ cAMP pathway in the skeletal muscles, the liver and the pancreas.

What is the Molecular mechanism of DNA replication?
kolezko [41]

Answer:

DNA replication a process of copying of a cell's DNA.  DNA replication is semiconservative process which means that each strand in the double helix helps in the synthesis of new, complementary strand and conserve the parent template.

The Molecular mechanism of DNA replication is as following:

  1. The double starnded DN in binded with hydrogen bond, the enzyme helicase opens up the DNA at the replication fork.
  2. A single stranded binding protein prevent the rewinding of DNA and so binds to the DNA around the replication fork
  3. Topoisomerase prevent supercoiling at replication fork.
  4. The ezymes primase come in action and produces RNA primers which are complementary to the DNA strand.
  5. DNA polymerase III help to extends the primers and allow them to add  to the 3' end, to make new DNA.
  6. DNA Polymerase then remove RNA primers and replace with DNA.
  7. DNA ligase blocks the the gaps between DNA fragments.

So, this is the molecuar mechanism of DNA replication.
