Imagine that a convicted child molester is released from jail and
that he is now traveling around the country looking for work. One day

of evidence at the crime scene is a semen specimen on the boys clothes.
Now this specimen could be useful if the police tracked down, and arrested

data bank is necessary it is important to know exactly what DNA is.
Firstly, there are cells which makes up all organisms and inside these
cells are chromosomes. Chromosomes, which are made up of DNA, contain all
the hereditary information that an individual has. Now this DNA
(Deoxyribonucleic acid) which makes up these chromosomes simply contains
the blueprints of the organism. It is DNA which determines what, where,
and when to make a certain protein, and it basically is the storage center

individuals have unique DNA, is that each cell in an organism has
identical DNA....
