Why is satellite DNA able to be isolated from other DNA in a density gradient? What is cryptic satellite DNA?
What will be an ideal response?
Ans: In the density gradient, DNA is isolated based on differences in G-C content, so satellite DNA has a different G-C content than most DNA. Cryptic satellites have a similar G-C content to that of nonrepetitive DNA, but have the features of satellite DNA (i.e., long arrays of tandem repeats).
