The expression of genes has to be very carefully controlled by cells; serious problems can arise when genes are expressed in the wrong places, at the wrong times, or at the wrong levels, for some ...

Tail loss in gorillas, chimpanzees, and humans is believed to have occurred about 25 million years ago, when the group evolved away from Old World monkeys. A genetic change in our ancient ancestors ...

'Random DNA' is naturally active in the one-celled fungi yeast, while such DNA is turned off as its natural state in mammalian cells, despite their having a common ancestor a billion years ago and the ...

Long non-coding RNAs (lncRNA) are a type of RNA molecule that do not carry instructions to make proteins. Instead, they influence how other genes are expressed. There are tens of thousands of lncRNAs ...

A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys. A genetic change in our ancient ancestors may partly explain why humans don't have tails like ...
