The conventional central dogma of molecular biology dictates that the genetic information contained within deoxyribonucleic acid (DNA) is passed onto messenger ribonucleic acids (mRNAs), which are then used as templates to synthesize proteins. Although these types of protein-coding genes have been historically prioritized in typical phenotype-genotype studies with a parallel disregard to the rest of the genome, the completion of genome projects has unveiled a surprising layer of genetic information that can play critical roles in cellular processes without coding for proteins. These types of genes are called noncoding genes as they do not code for proteins. Noncoding genes come in different sizes and shapes, and they are just as versatile in carrying out cellular biochemical processes as proteins. In this Chapter, we cover a comprehensive review of housekeeping and regulatory noncoding genes and their mode of action.
