Gene expression. Computer artwork showing the process of transcription,the first stage or gene expression. Here,a chromosome (distance,centre-left) is unravelled to reveal the histones (blue spheres) around which the DNA (deoxyribonucleic acid,orange) is wrapped to package it within the chromosome. The DNA is then further unravelled to reveal its double-stranded helix (centre left),which is then 'read' by an RNA polymerase enzyme (not shown) to produce a complementary,antiparallel RNA (ribonucleic acid) strand (lower centre-right),known as messenger RNA (mRNA). The mRNA will then be translated to produce the protein molecule that corresponds to the gene being read | |
