differance between repetetative and satellite DNA
Answers
hey buddies here is u r answer
Repetitive DNA is the part of the DNA which has repetitin of the base pairs no matter how much and in what way like palindrome repeats or mirror repeats or trinucleotide repeats or simple repeats…
Satellite DNA is the part of the repetitive DNA which is very specific in nature; DNA that contains many tandem (not inverted) repeats of a short basic repeating unit. Satellite DNA is located at very specific spots in the genome (on chromosomes 1, 9, 16 and the Y chromosome, the tiny short arms of chromosomes 13-15 and 21 and 22, and near the centromeres of chromosomes). Satellite DNA is highly repetitive DNA sequences found in heterochromatin, composed of simple sequences (very short) repeated in tandem many times to form large blocks of sequence. Additionally, following the accumulation of mutations, these blocks of repeats have been repeated in tandem themselves. The degree of repetition is on the order of 1000 to 10 million at each locus. Loci are few, usually one or two per chromosome. They were called satellites since in density gradients, they often sediment as distinct, satellite bands separate from the bulk of genomic DNA owing to a distinct base composition.
