DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning ...

A portion of our genome that was once dismissed as being “junk” may actually play an important role in regulating gene expression, new research suggests. According to the work of an international team ...

For decades, biologists have known that the instructions for life are written in DNA, yet the vast majority of those letters seemed to sit in the dark, doing little that was obvious. Now a new ...

Repeats of DNA sequences, often referred to as "junk DNA" or "dark matter," that are found in chromosomes and could contribute to cancer or other diseases have been challenging to identify and ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics-meticulously placed chemical tags that influence which genes are expressed in ...
