Solution
The correct option is D Cell from where DNA is extracted
Satellite DNA is the highly repetitive DNA consisting of short sequences repeated a large number of times. Base composition (A:T rich or G:C rich), length of segment, number of repetitive units are different criteria used for classifying satellite DNA into mini and micro satellites.
Variable number tandem repeat (VNTR) is a minisatellite which usually has repeat unit size of about 10-100 bp.
Short tandem repeats (STRs) are microsatellites whose unit repeat size is usually about 2-6 bp.
Source of DNA is not a criteria for classifying satellite DNA.
