Question

DNA replication involves producing new copies of DNA molecules. How many individual DNA strands exist after one molecule of DNA has been replicated? A. 3 B. 4 C. 2 D. 1

Answer 1

Answer: option C) 2

Step-by-step explanation:

DNA undergoes semi-conservative replication where the double-stranded parent DNA splits in two.

Then, the nucleotide sequence on each strand is read by the enzyme, DNA polymerase and newly synthesized strand that is complimentary to the splitted parent strand is generated and paired to it.

Thus, semi-conservative replication ends with two (2) new daughter DNA strands produced.
