Answer :

A double-stranded DNA molecule with three guanine and five thymine nucleotides (on one 5' to 3' strand) has 16 nucleotides in total.

What is a nucleotide?

A nucleotide is the monomer constituting DNA or RNA biopolymer molecules.

Each nucleotide consists of the following:

  • A nitrogenous heterocyclic base; which can be either a double-ringed purine or a single-ringed pyrimidine
  • A five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA)
  • A phosphate group

A double-stranded DNA molecule posseses two strands of DNA made up of nucleotides.

According to this question, a double-stranded DNA molecule has three guanine and five thiamine nucleotides.

This means that each stand of DNA has 8 nucleotides, hence, the double-stranded DNA will have 16 nucleotides in total.
