Each nucleotide contains one nitrogenous base; hence, 8 nucleotides will have 8 bases.
Explanation:
Nucleotides are the primary structural building block of a DNA molecule.
A nucleotide is a polymer compound comprising of a nitrogenous base attached to a pentose sugar group and a phosphate group attached by chemical bonds.
In a DNA double helix strand, the outer framework is constituted by the sugar and phosphate molecules while the bases form the inner or the rungs of helix.
The nitrogenous bases stores the information that carries the required trait or phenotype to be formed in an organism.
There are two main groups of nitrogenous bases - purine (like adenine, guanine) and pyramidine (thymine, cytosine) bases, and one from each group is joined while pairing.
On a single double helix DNA strand, there are two pairs of DNA nitrogenous bases. So, 8 DNA bases will have 4 pairs of bases or 8 single bases.
