This is done when the message, written in the DNA double helix, is transcribed into a related 'messenger' molecule, called RNA.

To turn a stretch of double-stranded DNA into a protein, cells first have to build a copy of it using a single-stranded molecule called RNA.

When genes, which are made of DNA, are active they make a chemical messenger called RNA that tells the cell to make a particular protein.

There are two main families of polynucleotides in living cells, called DNA and RNA for short.

Each little neuron contains, among other things, about twenty million molecules of ribonucleic acid, called RNA for short.

This test measures the genetic material of the virus called RNA (ribonucleic acid) and is often called the "viral load".

Scientists at several labs established this with a technique called RNA in situ hybridization.

The vertical, curved strand was called RNA, ri-bonucleic acid.

Studies suggest that treacle is involved in the production of a molecule called ribosomal RNA (rRNA) within cells.

A common misconception is that the new engine was called RNA which is incorrect, RNA refers only to the renderer.
