Question

Which of the following statements about primers are correct? Select all that apply.____

a. They are needed for the start of DNA synthesis.
b. They are synthesized by an enzyme called primate.
c. They are synthesized by DNA polymerase.
d. They are needed for the start of DNA synthesis.
e. They provide a 3-OH group for attachment of DNA nucleotides.

Answer 1

Primers are short sequences of RNA or DNA nucleotides that are needed for the start of DNA synthesis. They provide a 3'-OH group for attachment of DNA nucleotides by DNA polymerase. Primers are synthesized by RNA primase, which is an RNA polymerase.

Step-by-step explanation:

Primers are short sequences of RNA or DNA nucleotides that are needed for the start of DNA synthesis.

They provide a 3'-OH group for attachment of DNA nucleotides by DNA polymerase.

Primers are synthesized by RNA primase, which is an RNA polymerase.
