DNA polymerase III can synthesize new DNA at a rate of 1000 bases per second. The genome of Escherichia coli is about 4,600,000 base pairs in length. How long should it take to replicate the E. coli genome

Respuesta :

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.
