Q.
E.coli has only $4.6 \times 10^6$ base pairs and completes the process of replication within $18$ minutes; then the average rate of polymerisation is approximately-
E. coli that has only $4.6 \times 10^6 bp$ (compare it with humans whose diploid content is $6.6 \times 10^9 bp$ ), completes the process of replication within 18 minutes; that means the average rate of polymerization has to be approximately 2000 bp per second.
