are at least 10 types of human satellite DNA.
Typically they make up 10 - 15 % of
mammals genomes. It is satelite
DNA that is used in one type of DNA finger printing.
Interspersed Elements (SINEs) - These approximately 300 bp units of DNA are found distributed throughout the
genome. An example is the human Alu sequence which occurs about 500,000
times making up 5 % of the genome in the human genome. One of the interesting properties of SINEs
is that they may move about in the
Interspersed Elements (LINEs) - are longer than SINEs (up to 7,000 bp). There are approximately 50,000 copies of
the most common LINE family, L1, so this group makes up 5 % of the human
