How much time does E. coli take to complete the process of replication?

Options

  1. A18 minutes
  2. B20 minutes
  3. C40 minutes
  4. D80 minutes

Correct answer

A. 18 minutes

Step-by-step solution

In living cells, such as E. coli, the process of replication requires a set of catalysts (enzymes). The main enzyme is referred to as DNA-dependent DNA polymerase, since it uses a DNA template to catalyze the polymerisation of deoxynucleotides. These enzymes are highly efficient enzymes as they have to catalyze polymerisation of a large number of nucleotides in a very short time. E. coli that has only 4.6 ×106 bp (compare it with humans whose diploid content is 6.6 × 109 bp), completes the process of replication wi
