Every cell in an organism's body has the same copy of DNA, yet different cells do different things; for example, some function as brain cells, while others form muscle tissue. How can the same DNA make different things happen? ...

In nearly every organism's genome, scattered between genes that encode proteins, long regulatory regions stretch across expanses of DNA. Understanding what role these so-called enhancer regions play in controlling the activation ...

RNA, once considered a bit player in the grand scheme by which genes encode protein, is increasingly seen to have a major role in human genetics. In a study presented in the April 25 issue of the journal Cell, researchers ...

RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene ...
