(b) Messelson and Stahl, 1957
(c) Nirenberg and Khorana, 1967
(d) Watson and Crick, 1952

Answer 1

it was by messelson and stahl.....but in 1958...

Answer 2

Semi-conservative model of DNA was proposed by Messelson and Stahl in 1957.

Watson and Creek established that structure of DNA is double helix and made of nucleotides.

However, the experiments of Messelson and Stahl established that a DNA strand copied itself into two strands, among which the original strand and a new DNA strand are present.
