"18. Deoxyribonucleic acid, or DNA, is a molecule that encodes the genetic information in all living organisms. DNA genotype can be obtained from any biological material such as bone, blood, semen, saliva, hair, skin, etc. Now, for several years, DNA profile has also shown a tremendous impact on forensic investigation. Generally, when DNA profile of a sample found at the scene of crime matches with DNA profile of the suspect, it can generally be concluded that both samples have the same biological origin. DNA profile is valid and reliable, but variance in a particular result depends on the quality control and quality procedure in the laboratory. (self emphasis supplied)
"Deoxyribonucleic acid, or DNA, consists of long ribbon-like molecules, the chromosomes, 46 of which lie tightly coiled in nearly every cell of the body. These chromosomes - 23 provided from the mother and 23 from the father at conception, form the genetic blueprint of the body. Different sections of DNA have different identifiable and discrete characteristics. When a criminal leaves a stain of blood or semen at the scene of the crime it may prove possible to extract from that crime stain sufficient sections of DNA to enable a comparison to be made with the same sections extracted from a sample of blood provided by the suspect. This process is complex and we could not hope to describe it more clearly or succintly than did Lord Taylor C.J. in the case of Deen (transcript: December 21, 1993), so we shall gratefully adopt his description.
