Question

What is DNA replication?

• A. The process during which DNA strand winds around a core of histone molecules
• B. The process during which the hydrogen bonds between the nucleotides of two strands break
• C. The process by which a double-stranded DNA molecule is copied into two, identical DNA molecules.
• D. The process during which the bonds between the nitrogen base and deoxyribose sugar break

Answer 1

The correct option is C

The process by which a double-stranded DNA molecule is copied into two, identical DNA molecules.

During replication, the DNA double helix opens at one end, making the two strands free to which new strands begin to form and the process continues in a sequence for the whole length of the DNA.
