There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

Humanized mouse models are essential for investigating human gene function; however, the complete replacement of mouse genes ...

Scientists first read the human genome, a three-billion-letter biological book, in April 2003. Since then, researchers have steadily advanced the ability to write DNA, moving far beyond single-gene ...

David Liu and Richard Merkin of the Broad Institute of MIT and Harvard, along with Columbia professor Sam Sternberg, have developed a new, targeted means of inserting entire genes into human DNA ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

How much of our genome really matters? Some argue that because most of our DNA is active, it must be doing something important. Others say even random DNA would be highly active. This has now been put ...

University of Utah researchers at the Pulst-Scoles Laboratory have discovered that reducing levels of the STAUFEN-1 protein ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...
