Question

As DNA is replicated, which DNA base pair will bond to cytosine? adenine thymine cytosine guanine

Answer 1

Gunine form hydrogen bonds with cytocine triple bond &adnine form bond with thymine double bond

Answer 2

Answer: The correct answer is Guanine.

During DNA replication, the two complementary strands of DNA are separated. Each strand acts like a template strand. DNA polymerase enzyme adds nucleotides or dNTP ( deoxyribonucleoside triphosphate) which complement each strand and thus new strands are synthesized.

Addition of nucleotides take place according to Watson and Crick base pairing.

• Guanine makes bond with Cytosine.
• Adenine makes bond with Thymine.

Thus, Guanine is the correct answer as it pairs with Cytosine.
