Uses of DNA
- DNA profiling (genetic fingerprinting)
- Genomic sequencing and comparative genome mapping
- Genetic engineering
- Gene therapy
All DNA contains sections called genes, which code for polypeptides and protiens. Coding DNA only forma 1.5% of DNA in humans. Much DNA is non-coding, formerly known as junk, but is now known to have regulatory functions.
Genomics - the study of genomes - wants to map the whole genome of organisms; comparing genes and DNA sequences to understand the relationship between genes and health, behaviour and evolutionary roles between organisms.
