342994
The expts. performed on Vicia faba (faba beans) by Taylor and colleagues in
1 1956
2 1952
3 1953
4 1958
Explanation:
Very similar experiments involving use of radioactive thymidine to detect distribution of newly synthesised DNA in the chromosomes was performed on Vicia faba (faba beans) by Taylor and colleagues in 1958.

Isotopes used for proving semi-conservative replication of DNA are
1 \({ }^{14} \mathrm{N}\) and \({ }^{31} \mathrm{P}\)
2 \({ }^{14} \mathrm{~N}\) and \({ }^{14} \mathrm{C}\)
3 Radioisotopes \({ }^{14} \mathrm{~N}\) and \({ }^{15} \mathrm{~N}\)
4 Heavy isotopes \({ }^{14} \mathrm{~N}\) and \({ }^{15} \mathrm{~N}\)
Explanation:
Meselson and Stahl proved this by using cultured in E. coli in a cultural medium containing \(^{{\rm{15}}}{\rm{N}}\) isotopes of heavy nitrogen . After the DNA replication of E.coli for some generations in \(^{{\rm{15}}}{\rm{N}}\) medium, it was found that both strands of DNA had \(^{{\rm{15}}}{\rm{N}}\) as constituent of purines and pyrimidines. Therefore, such DNA formed was found to be hybrid as one strand was made up of \(^{{\rm{15}}}{\rm{N}}\) (old) and the other was made up of \(^{{\rm{14}}}{\rm{N}}\) (new)
