How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals ...

DNA and RNA are nucleic acids found in the nucleus of the cells in every living organism. Both nucleic acids participate in the coding, decoding, regulation and expression of genes. Lipid ...

Chemists say they have solved a crucial problem in a theory of life’s beginnings, by demonstrating that RNA molecules can link short chains of amino acids together. The discovery “opens up ...

Until now, DNA and RNA epigenetics were studied as independent systems. These two mechanisms seemed to function separately, each playing its own role in distinct stages of the gene regulation process.

DNA may have mixed with RNA to produce the first life on Earth Key building blocks of DNA and RNA can be made from the same raw materials. This finding suggests that instead of one or the other ...
