| what can be the source
of DNA? |
| |
DNA can be extracted from virtually any part of
human body. The most common source of DNA is blood or soft tissue samples.
DNA can be also extracted from semen, saliva, hair roots and even from
several skin cells left on the surface of a pint glass after it was
touched (these sources of DNA are commonly employed in forensic
analysis).
Medical Genomics uses mouth swabs (or “buccal”
swabs as they are called in scientific literature) to extract DNA.
This is a very simple, completely painless and quick procedure which
involves brushing the inside of the cheek 10-20 times with a cotton
wool bud to collect skin cells. There will be enough DNA collected by
this procedure to perform genotyping for more than a hundred times.
