Question

Bidirectional DNA synthesis by eukaryotic DNA polymerase (replicase) refers to: synthesis of both the leading and lagging strands of DNA at a replication fork. joining of two Okazaki fragments along the lagging strand. movement of two replication forks out from one origin of replication. activity of type II topoisomerases ahead of replication forks. All of the above Biosynthesis of cholesterol takes place in the cytosol in four stages. The first stage is a condensation stage in which three ___ (1) ___ condense to form ___ (2) ___. (1) pyruvate: (2) malonyl-CoA (1) acetyl-CoA: (2) malonyl-CoA (1) malonyl-CoA: (2) mevalonate (1) pyruvate: (2) mevalonate (1) acetyl-CoA: (2) mevalonate

Explanation / Answer

The answers
Question 4:
synthesis of both the leading and lagging strands of DNA at a replication fork.
DNA polymease synthesizes a continous strand from 5'-3' direction, this is called leading strands, and the same DNA polymease synthesizes small fragments in opposite direction. This strand is called lagging strand.

Question 5:
acetyl CoA, mevalonate

Two Acetyl Co A will form Acetoacetyl Co A, this Acetoacetyl Co A forms Mevalonate with another acetyl Co A.
