Which property of DNA double helix led hypothesise DNA Watson and Crick to semiconservative mode of replication? Explain.

Text Solution

Verified by Experts

(a) Double helical structure of DNA.
(b) Specific base pairing between the bases of two polynucleotide chains.
In DNA replication, the parental strand is conserved while the other complementary strand is formed anew. This indicates the semiconservative mode of DNA replication.
