They say that life comes without an instruction manual, but that's not entirely true. Each cell in our bodies lives according to instructions issued by its DNA in the form of RNA molecules. RNA was recently thrust into the ...

The cells of female mammals have a dosage problem, because they have twice as many X chromosomes as are needed in the body. Consequently, one of them is randomly selected and switched off already during early embryonic development. ...

(Phys.org)—A pair of researchers at MIT has developed what amounts to a "kill switch" for genetically modified organisms (GMOs). In their paper published in the journal Nature Communications, Brian Caliando and Christopher ...
Certain diseases such as cystic fibrosis and muscular dystrophy are linked to genetic mutations that damage the important biological process of rearranging gene sequences in pre-messenger RNA, a procedure called RNA splicing.
