DNA’s chemical cousin, RNA, was the messenger that carries DNA instructions from the double helix in the cell’s nucleus to ...

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...

RNA polymerase structure and function (in transcription) The RNA polymerase enzyme is a large complex made up of multiple subunits 1. The prokaryotic form of RNA polymerase has four subunits capable ...

RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...

Because the newly discovered RNA molecules are born in one gene but may affect another distant gene, "the whole concept of a gene is really up for discussion here," says study leader Thomas ...

Noncoding RNA genes (ncRNA) are transcribed but are not translated. Another gene definition may decrease the number of noncoding RNA included in the human gene count; a gene can be considered any ...
