Two significant functions of Bioinformatics :
The biological information hidden in DNA / RNA and protein sequences are processed into genes and proteins and a relationship is established between a gene and protein by bioinformatics tools.
Using bioinformatics tools such as Genmark (for bacteria) and GenScan (for eukaryotes) gene prediction is carried out in organisms. GenScan can identify introns, exons, promoter sites and polyA signals and other gene identification algorithms.
