For providing evidence in favour of semiconservative way of $DNA$ replication, Taylor, Woods, and Hughes performed experiments on:

In Meselson and Stahl's experiments,heavy $DNA$ was distinguished from normal $DNA$ by centrifugation in

Ten $E. coli$ cells with $^{15}N$-dsDNA are incubated in a medium containing $^{14}N$ nucleotides. After $60$ minutes, how many $E. coli$ cells will have $DNA$ totally free from $^{15}N$ (in $cells$)?

Select the appropriate option regarding a primer.

Polymerisation of $DNA$ nucleotides during the synthesis of the lagging strand occurs in:

Experiments involving the use of radioactive thymidine to detect the distribution of newly synthesized $DNA$ in the chromosome were performed on which plant?
