Question

Short chain nucleotides (primers) are synthesized by primosome, which contains the enzyme primase. Specifically, primase is...

a. RNA polymerase enzyme
b. DNA polymerase enzyme
c. A DNA stabilizing protein
d. A short (8-10) chain of ribonucleotides

Answer 1

Primase is an RNA polymerase enzyme that synthesizes the RNA primer required to initiate DNA synthesis. The primer is a short chain of ribonucleotides that is complementary to the template DNA strand.

Step-by-step explanation:

Primase is an RNA polymerase enzyme that synthesizes the RNA primer required to initiate DNA synthesis. The primer is a short (8-10) chain of ribonucleotides that is complementary to the template DNA strand. It provides a free 3'-OH group to which DNA polymerase can add DNA nucleotides.
