Question

E. coli has only 4.6 × 10⁶ base pairs and completes the process of replication within 38 minutes; then the average rate of polymerisation is approximately

(1) 1000 base pairs/second

(2) 2000 base pairs/second

(3) 3000 base pairs/second

(4) 4000 base pairs/second

Comments

Actually question is wrong,E.coli completes its replication within 38 minutes.

---

2000basepairs /second

Answer 1

Answer (2) 2000 base pairs/second

Sol. The average rate of polymerisation of DNA in E.coli is 2000 bp per second. It has only 4.6 × 10⁶ bp and completes the process of replication within 38 minutes

Comments

It should be 4000 bp/sec.
4.6 x 106/18 x 60 = ~4000 bp/sec

---

question was wrong, instead of 18 minutes it should be 38 minutes. now the answer is right.

---

It is 38 mins in the qn not 18 min

---

Yes now I fixed the question

---

Yes bro u are right

Answer 2

Ans : (2) 2000 base pairs/second
