E. coli has only 4.6×1064 . 6 \times {10}^{6} base pairs and completes the process of replication within 1818 minutes; then the average rate of polymerisation is approximately:

Options

  1. A20002000 base pairs//second
  2. B30003000 base pairs//second
  3. C40004000 base pairs//second
  4. D10001000 base pairs//second

Correct answer

C. 40004000 base pairs//second

Step-by-step solution

Given,

Number of base pairs =4.6x106=4600000= 4 . 6x{10}^{6} = 4600000

Time =1818 minutes =18x60=1080= 18x60 = 1080 seconds

The average rate of polymerisation can be calculated using the formula:

Rateofpolymerisation = \dfrac{Numberofbasepairs}{Time}</p><p>=</p><p> == \dfrac{4600000}{1080} = 4259bp / s</p><pstyle="text−align:justify;">Itisapproximately</p><p style="text-align: justify;">It is approximately4000basepairs / second$.
