Satellite DNA Quiz

Satellite DNA is the main component of functional centromere.

Satellite DNA consists of very large arrays of tandemly repeating, non-coding DNA.

The name 'satellite DNA' refers to how repetitions of a short DNA sequence tend to produce a different frequency of the nucleotides and thus have a different density from bulk DNA, forming a second or 'satellite' band when genomic DNA is separated on a density gradient.
