When DNA replication starts
- A the phosphodiester bonds between the adjacent nucleotides break
- B the bonds between the nitrogen base and deoxyribose sugar break
- C the leading strand produces Okazaki fragments
- D the hydrogen bonds between the nucleotides of two strands break.
Answer & Solution
Correct Answer
(D) the hydrogen bonds between the nucleotides of two strands break.
Step-by-step Solution
Detailed explanation
(D) the hydrogen bonds between the nucleotides of two strands break.,
During DNA replication, the process begins with the breaking of hydrogen bonds between the nitrogenous bases of the two DNA strands. This unwinds the double helix and allows each strand to serve as a template for the synthesis of a new complementary strand.
