What is the error in above diagram?
In which type of $DNA$ replication of the two newly formed molecules one is purely a new one and the other one is old
The enzyme $DNA$ polymerase in $E.coli$ is a $DNA$ dependent polymerase and also has the ability to proof-read the $DNA$ strand being synthesised. Explain. Discuss the dual polymerase.
Bacteria were grown in a medium containing heavy isotope of nitrogen ($N^{15}$) for many generations and all their $DNA$ contained many heavy nitrogen only. A bacterium of this type was transferred to normal medium and allowed to duplicate. After two divisions of heavy $DNA$ is likely to be that
Leading strand during $DNA$ replication is formed
