Solution

The correct option is C repetitive DNA
DNA fingerprinting involves identifying differences in some specific regions in DNA sequence called as repetitive DNA. A small stretch of DNA is repeated many times in these sequences. They do not encode protiens.

During density gradient centrifugation of DNA, the repetitive DNA gets separated from bulk genomic DNA as different peaks. While the bulk DNA forms a major peak, the other small peaks formed are referred to as satellite DNA.

DNA polymorphism refers to the difference in DNA sequences among individuals, groups, or populations.

Nucleotides are monomers of nucleic acids like DNA and RNA. Each nucleotide consists of 3 components - a pentose sugar, a nitrogenous base and a phosphate group.
