Question

Which statement describes the semi-conservative replication of DNA? A. Parental DNA is broken down into nucleotides and reassembled with new nucleotides B. Parental DNA is split into triplets and new triplets are added C. Parental DNA is split into two strands, each of which is replicated D. Parental DNA remains intact and a new daughter DNA copy is built from new nucleotides
Options
A Parental DNA is broken down into nucleotides and reassembled with new nucleotides
B Parental DNA is split into triplets and new triplets are added
C Parental DNA is split into two strands, each of which is replicated
Correct Answer
D Parental DNA remains intact and a new daughter DNA copy is built from new nucleotides
Correct Answer

Option C is the correct answer.

Detailed Explanation

Semi-conservative replication means that when a DNA molecule replicates, each of the two parental strands serves as a template for a new complementary strand. The result is two daughter molecules, each with one old (parental) strand and one new strand.

Hint

Each new DNA molecule gets one old strand and one new strand.
