Assertion :- Tylor and colleages in 1958 used CsCl density gradient centrifugation technique to prove semiconservatie DNA replication.
Reason : They use `""^(15)N` heavy nitrogen which is not a radioactive isotope.

Isotopes used for proving semiconservative replication of DNA were :

isotopes used for proving for semiconservative replication of DNA are

Isotopes used in proving semi-conservation replication of DNA were

Who proved semiconservative mode of DNA replication for the first time in E. Coli with the help of N^15 heavy nitrogen isotope?

Who gave semiconservative mode of DNA replication for the first time in E. coli with the help of .^(15) N heavy nitrogen isotope ?

The semi-conservative nature of DNA replication was established by Meselson and Stahl in their classic experiment with bacteria. They grew bacteria in N^(15)-NH_(4)CI containing medium with N_(14) - containing compounds and allowed to grow for three generation . CsCI density gradient centrifugation of isolated DNA established the nature of semiconservation DNA replication. The pictorial representation below shows the positon of differentially labeled DNA in CsCI density gradient. Had the DNA replication been conservative, what would have been the pattern ?
