There are at least 10 types of human
Typically they make up 10

It is satelite DNA that is used in one type
of DNA finger printing.
Short Interspersed Elements (SINEs) - These approximately 300 bp units of DNA
are found distributed throughout the
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
Long Interspersed Elements (LINEs) - are longer than SINEs (up to 7,000
There are approximately 50,000
copies of the most common LINE family, L1, so this group makes up 5 % of the
