Question

Why DNA replication is said to bel semiconservative? How Meselson and Stahll provided evidence in favour of semiconservative nature of DNA replication?​. 5 mrks

Answer 1

Answer:

DNA replication is semi-conservative because in the replication process the resulting DNA helix is composed of both a new strand and an old strand. This occurs because of the complementary base pairing, I.e. each nitrogenous base only pairs with its complementary pair.

Answer 2

DNA replication is said to be semi conservatives because .

Whenever new DNA is synthesized one strand of dna comes from parental and other strand of dna is newly synthesized that's why it is called semi conservative.

They perform the evidence by using Nitrogen heavy isotope having mass 15g.

They find when new DNA is synthesized it's one strand have Nitrogen that heavy isotope where other strand have normal isotopes.
