Answer:
1.27 hour or 77 minutes.
Explanation:
In the given question it is provided that:
1. DNA polymerase III synthesizes new DNA at a rate of- 1000 bases/sec
2. The genome of E.coli has- 4,600,000 base pairs
To calculate the time required for replication:
Total base pairs/ speed of enzyme
= 4600000/1000
= 4600 seconds
= 4600/3600 (1 hour= 3600 seconds)
= 1.27 hour or 77 minutes.
Thus, 1.27 hour or 77 minutes is correct.
