DNA finger Printing Facts and progress of DNA finger printing. Facts of all DNA finger printing up to 2003.

The genetic material that makes up a persons inherited features (sex, eye color and blood type) is called DNA. (Deoxyribonucleic Acid) DNA is a long molecule that is made up of building blocks called nucleotides. What order the nucleotides are in is extremely important. Grouped together the nucleotides form genes. Every persons DNA contains over 40,000 genes. Each inherited feature is determined by one or more gene. The order of the nucleotides in the DNA is …

…in error increases as the amount of DNA collected decreases. There is a greater risk of contamination when duplicating a very small amount of DNA to analyze it. DNA finger printing has been used to identify unknown people (such as military personnel killed in action or crime victims) for this reason a DNA database is now being developed. DNA finger printing is more accurate than dental records, blood typing or dog tags for this purpose.
