Transcription

Transcription is the process by which single mRNA is coded from double stranded DNA. This process is highly regulated and controlled to ensure the right amount of a specific gene is coded for at a specific time.

Proteins are synthesised in the cytosol, however, DNA does not leave the nucleus, therefore a copy of the gene coding for the desired protein is sent as a messenger to the cytosol from the nucleus. This is called messenger RNA 'mRNA'
