During the process of transcription, DNA is converted to RNA, a complex molecule that is able to carry genetic information outside of the cell's nucleus. This page guides you through the biochemical ...

During elongation, the new RNA strand becomes longer and longer as the DNA template is transcribed. In this view, the 5' end of the RNA strand is in the foreground. Note the inclusion of uracil (yello ...

The RNA polymerase enzyme is a large complex made up of multiple subunits 1. The prokaryotic form of RNA polymerase has four subunits capable of transcribing all types of RNA. In eukaryotes, these ...

Next, RNA polymerase adds nucleotides complimentary to the 3’ end of the template DNA strand to form the corresponding mRNA strand. The process goes on as the RNA polymerase advances along the DNA ...

The answer lies in differential gene expression – the combination of genes that are turned on (expressed) or turned off (repressed) in particular cells – this is what makes each cell unique. Gene ...
