While analysing the DNA of an organism a total number of 5386 nucleotides were found out of which the proportion of different bases were: Adenine = 29%, Guanine = 17%, Cytosine = 32%, Thymine = 17%. Considering the Chargaff’s rule it can be concluded that:

Options

  1. Ait is a double-stranded circular DNA
  2. BIt is single-stranded DNA
  3. CIt is a double-stranded linear DNA
  4. DNo conclusion can be drawn

Correct answer

B. It is single-stranded DNA

Step-by-step solution

The DNA is single stranded as the composition does not go with rule of equal number of purines and pyrimidines.
