LIFE SCIENCE

Detailed explanation-1: -DNA microarray technology, also known as the DNA chip, is the latest in nanotechnology that allows researchers the have ability to study the genome in a high throughput manner. It can be used for gene expression profiling which gives scientists insights into what genes are being up or down-regulated.

Detailed explanation-2: -Biotechnology is used by forensic scientists to collect or process trace evidence such as hair, skin, blood or semen samples, which is found at crime scenes. An important aspect of modern forensics is the use of DNA profiling, or genetic fingerprinting.

Detailed explanation-3: -DNA fingerprinting was first used in forensic science in 1986 when police in the UK requested Dr. Alec J. Jeffreys, of University of Leicester, to verify a suspect’s confession that he was responsible for two rape-murders. Tests proved that the suspect had not committed the crimes.
