Much of the human genome is made of regulatory regions that control which genes are expressed at a given time within a cell. Those regulatory elements can be located near a target gene or up to 2 mill...
Despite the sheer number of genes that each human cell contains, these so-called “coding” DNA sequences comprise just 1 percent of our entire genome. The remaining 99 percent is made up of “non-coding...
Researchers shed new light on regulation of repetitive DNA sequences
Researchers repetitive DNA sequences
2016/2/22
A pair of studies by a team of scientists has shed new light on the nature of a particular type of DNA sequences—tandem DNA repeat arrays—that play important roles in transcription control, genome org...
RNA, once thought to be a mere middleman between DNA and protein, is now recognized as the stage at which a host of regulatory processes can act to allow for flexibility in gene expression and thus th...
