Question

In E. coli (~4.6 × 10⁶ bp), DNA replication is completed in approximately 18 minutes, giving an average rate of:

Accepted Answer

C. 2000 bp/s

Time = 18 min × 60 s = 1080 s.
Rate = 4.6 × 10⁶ / 1080 ≈ **~4250 bp/s for the whole molecule**, but DNA replicates bidirectionally from origin
→ each polymerase moves at ~**2000 bp/s**.

Answer

200 bp/s

Answer

20 bp/s

Answer

20 000 bp/s
