Question

4. Short strands of ——- primer are used in DNA replication.
a. DNA
b. RNA
c. Histone
d. Protein​

Answer 1

Answer:

It's option (b) RNA

Explanation:

Answer 2

Answer:

b. RNA

Explanation:

A primer is a brief nucleic acid collection that gives a place to begin for DNA synthesis.

In dwelling organisms, primers are brief strands of RNA. A primer ought to be synthesized via way of means of an enzyme known as primase, that's a form of RNA polymerase, earlier than DNA replication can occur.

Because DNA polymerase can handiest synthesize DNA in a 5′ to 3′ direction, the opposite new strand is prepare in brief portions known as Okazaki fragments. The Okazaki fragments every require a primer made from RNA to begin the synthesis. The strand with the Okazaki fragments is called the lagging strand.

So,the correct answer is option b.RNA.
