Q: A bacteria has genome of size 6 million bp. If DNA synthesis rate is 1000 bp/ second. How long does it take (in minutes) for replication of genome?

Ans: Size= 6000000bp
Speed= 1000bp/second
Time needed= 6000000/1000 seconds = 6000 seconds = 100 mins


Here the assumption is that there is only one replication fork.

Keep a note in future that, each replication fork works independently at the same pace. Therefore, had there been 2 replication forks, time taken would have been 100/2 mins I.e 50mins . 33.33 mins for 3 forks and 25mins for 4 forks and so on..
