Does all DNA have a function? Is all of the DNA in your genome, for example, part of a gene?

Answer 1

Hi Jordan,

A small portion of the human genome is made up of genes that encode information for the production of proteins, which are known as protein-coding genes. However, not all of the remaining DNA is made up of non-coding genes. Some DNA does not encode proteins but can still have important functions, such as producing certain types of RNA or regulating gene expression. Other non-coding DNA may be found within genes, such as introns, which are removed from the pre-messenger RNA during RNA processing before a protein is produced. Therefore, not all DNA is part of a gene, and not every gene produces a functional protein.
