E. coli completes replication of its 4.6 x 10^6 bp genome in 18 minutes. The average polymerisation rate is closest to:
A{'text': '2000 bp per second', 'label': 'A'}
B{'text': '200 bp per second', 'label': 'B'}
C{'text': '20000 bp per second', 'label': 'C'}
D{'text': '200000 bp per second', 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': '2000 bp per second', 'label': 'A'}
Rate = 4.6 x 10^6 bp / (18 x 60 s) which is approximately 4260 bp per second per fork; averaged across the bidirectional replication this is on the order of 2000 bp per second, as stated in NCERT.
