Question

Which of the following is true about DNA replication?

Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of DNA.
DNA replication allows for the formation of hydrogen bonds to copy two old strands of DNA.
DNA polymerase is an enzyme that works to transport DNA from the nucleus to the cytoplasm.
The double helix results from two old strands of DNA fused together to form two new strands.
(ITS NOT D)

Answer 1

Answer:

its A

Explanation:

because its helicase enzyme which causes the unwinding(opening up) of the dna double strands by breaking the hydrogen bonds formed btn the paired bases.

C is wrong because dna polymerase controls replication whereby it links the dna nucleotides to form long strands of dna.

the rest r just wrong........because they r wrong lol

Answer 2

Answer:

Your answer would be A!

Explanation:

Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of DNA.
