Let me correct your question adenine has to be 120 and not 10
Chargaffs rule says

Adenine (A) pairs with Thymine (T)
Cytosine (C) pairs with Guanine (G)

The question says Adenine = 120 and cytosine is 120

A= T which is A= 120 and T is also 120
C= G  which is C= 120 and G will be 120

therefore total number of nucleotides = A + T+C+G
  = 120 + 120+120+120
  Total number of nucleotides   = 480

Answer:

:

The circular chromosome of the bacterium Escherichia coli consists of a DNA molecule approximately 4.6 million nucleotides long.

  • In addition to the main chromosome, bacteria are also characterised by the presence of extra-chromosomal genetic elements called plasmids.
