.... Harvard Medical School in the United States said on Wednesday that

within junk DNA in the yeast genome, they have discovered a new class of

gene. 

Unlike other genes, the new one does not produce a protein or enzyme to

carry out its function. But when it is turned on, it regulates a

neighbouring gene. ...

There are about 30,000 to 40,000 genes in the human genome. Much of the

genome consists of junk DNA, which scientists are trying to decipher to

determine the causes and potential treatments for human diseases. 

The new gene, called SRG1, blocks the function of the adjacent gene in the

yeast genome....

The new gene works by making RNA, a cousin of DNA, which represses or turns

off the adjacent gene. ...
