Question

Which step happens first in DNA replication?
A) Initiation
B) Elongation
C) Termination
D) None of the above

Answer 1

The first step happens first in DNA replication is

(A) Initiation

Answer 2

Initiation happens at the beginning of DNA replication.

During the process of replication of the DNA, the helicase enzyme separates the stands of the DNA.

Thereafter, complementary nucleotides are added by the DNA polymerase to the already separated DNA strands.  

After finishing adding the nucleotides, two identical molecules of DNA are formed.

The adenine bonds with the thymine the bases on the nucleotides.
