A similar experiment to that of Matthew Meselson and Franklin Stahl was conducted in 1958 by a scientist who worked on Vicia faba (faba beans). Who was this scientist?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Taylor.
In 1958, Meselson and Stahl showed in E. coli that DNA replicates semiconservatively: each new DNA molecule keeps one old strand and makes one new strand. In the same year, Taylor and colleagues did very similar experiments on Vicia faba (faba beans). They used radioactive thymidine to trace newly made DNA in the chromosomes. Their results proved that the DNA in chromosomes also replicates semiconservatively.
NCERT Extract:
The Experimental Proof – “… 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. The experiments proved that the DNA in chromosomes also replicate semiconservatively.”
