CSI Malaysian Style

By Aniza Damis

If you have watched the popular television series Crime Scene Investigation (CSI), you will have learnt that if a person even so much as sneezes, spits, urinates or puts his sweaty hands against a wall, he will have left enough evidence for forensic investigators to identify him.

Provided that they can match the left-behind sample with a sample obtained from that person.

The science that takes these seemingly inconsequential discards of human activity and scrutinises them in a forensics laboratory, singling the samples out to one genetic identity is known as DNA profiling.
