When it comes to evidence of a crime, what is the #1 BEST source for lifting DNA of the following choices? ~

Whatever is available. The first two may not provide any. It also depends on whether you are searching for victim DNA or perp DNA. Don't you watch crime shows?

This is DNA evidence. Not lifting DNA.

Lifting DNA would come from tape, or Q-tip swabs or some type of agent that takes DNA samples.

The stuff you mentioned are sources of DNA.

I'd go with the saliva or blood evidence.

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.
