A Symposium on the Chemical Basis of Heredity. The isotope of nitrogen had an extra neutron in the nucleus, which made it heavier. The conservative hypothesis proposed that the entire DNA molecule acted as a template for the synthesis of an entirely new one. By using this site, you agree to the Terms of Use and Privacy Policy. Since nitrogen is found in the nitrogenous bases of each nucleotide, they decided to use an isotope of nitrogen to distinguish between parent and newly copied DNA. In the semiconservative hypothesis, proposed by Watson and Crickthe two strands of a DNA molecule separate during replication. Nitrogen is a major constituent of DNA.

Cold Spring Harb. In semiconservative replication, when the double stranded DNA helix is replicated, each of the two new double-stranded DNA helices consisted of one strand from the original helix and one newly synthesized.

    Cold Spring Harb. DNA from cells after two replications had been completed was found to consist of equal amounts of DNA with two different densities, one corresponding to the intermediate density of DNA of cells grown for only one division in 14 N medium, the other corresponding to DNA from cells grown exclusively in 14 N medium.
