Bioinformatics is a discipline that uses computers and software for understanding data collected in biological studies. Being an interdisciplinary field, it combines math, engineering, and computer science. As well as being an umbrella term, it specifically refers to analysis pipelines that are repeatedly used in genetics and genomics. In this case, bioinformatics are used to identify the location of SNPs. This helps identify the genetic component of diseases as well as differences between populations. Bioinformatics can help to sequence genomes and observe mutations. It can also be used to compare genetic and genomic data. It aids in the modeling of DNA, RNA and protein structures as well.
