Question

chromosones DNA types and regions within these types

Accepted Answer

chromosomes made up of DNA base pairs, small fraction are exons (genes that code for protein) and most introns (non-coding regions of DNA removed from mRNA before translation
within introns are satelite DNA (short sequences of DNA repeated many times), at minisatellite (region), sequence of 20-50 base pairs repeated 50 - hundreds of times (also known as variable number tandem repeats, VNTRs)
microsatellite is region with 2-4 base pairs repeated much less (also known as short tandem repeats, STRs)
number of repeats of mini/micro satellites differs due to different lengths of repeats inerited, so more similar satellite patterns between more closley related individuals
