Amolecule of dna was found to contain 120 adenine and 120 guanine bases. how many nucleotides comprise this molecule of dna?

480 nucleotides comprise this molecule of dna

Explanation:

According to Chargaff rule,

Given in the question

Adenine residue = 120

Cytosine residue = 120

So, [A] = [T]

i.e. [A =120] = [T=120]

again, [C] = [G]

i.e. [C=120] = [G=120]

hence, total number of nucleotides present

=> [A] + [T] + [C] + [G]

=> 120 + 120 +120 +120

=> 480.
