Normally, during DNA replication, the RNA primer is made by the enzyme primase. If the primase in a cell was defective, could its function be successfully taken over by RNA Polymerase II? Explain why, or why not.

Solution

DNA REPLICATION:IN DNA synthesis requires a smaller segment of RNA called RNA primer.the primer is synthesized by enzyme primase.it is also called as specialized RNA polymerase.the length of primer varies from10-60 nucleotides.the synthesis always occur from 3 end to 5 end.

FUNCTIONS OF ENZYME PRIMASE: Primase is an enzyme that copy DNA strand by making an RNA strand complementary to it.

Primase enzyme is active only in the presence of protein.parental straands are used as templates for the process.

In the absence of primer RNApolymerase 2 can initate the synthesis of new strand of RNA.

due to the absence of primer due to cell defective the RNA POLYMERASE 2 can perform the functions of primer.
