Advanced Look --> 1.) The mRNA
Before translation of the mRNA molecule can begin,
it must fit certain requirements. The following images attempt to illustrate
some of these required post-processing features. Clicking on each of
the thumbnail images will bring up a larger, labeled version of the described
see the Flash movie for the following sequence of images,
Eukaryotic mRNA has unique features. Before
it can be translated, it must be processed and modified.
One of the specific features it must have is a Poly
The 'readable' portion of mRNA consists of codons for
inidvidual amino acids, show here with colors. Each color represents a codon
for a unique amino acid.
A cap is also added to the mRNA. This cap is
neccessary for the stability of the mRNA molecule.
