Overview
Our genome is littered with scraps of DNA, termed "junk" DNAs, that serve no apparent purpose. Junk DNAs-make up as much as 98.5% of our genome. Scientists believe that some junk DNAs came into existence millions of years ago, when viruses inserted their DNA into that of the human host. There is emerging evidence that suggests that these bits of microbial DNAs may alter our functional genes, impacting our body physiology and behaviour.Synopsis
