NEETZoologyMolecular Basis of Inheritance
What was the main conclusion of the experiments performed by Meselson and Stahl and Taylor and colleagues?
Options
- ADNA replicates conservatively
- BDNA replicates randomly
- CDNA replicates semiconservatively
- DDNA replicates differently in different organisms
Correct answer
C. DNA replicates semiconservatively
Step-by-step solution
If E. coli was allowed to grow for 80 minutes then what would be the proportions of light and hybrid densities DNA molecule? Very similar experiments involving use of radioactive thymidine to detect distribution of newly synthesized DNA in the chromosomes was performed on Vicia faba (faba beans) by Taylor and colleagues in 1958. The experiments proved that the DNA in chromosomes also replicate semiconservatively
