Section 4 - Protein Synthesis
To best appreciate the contents of this chapter you need to INTERACTIVELY
EXAMINE a number of structures. If you haven't done so already, we STRONGLY
URGE you to install the FREE molecular viewer software packages, RasMol
and Mage, and configure them to be automatically invoked by chemical/MIME.
See our Technology Page to find
out how.
Section 4 concerns the processes involved in Protein Synthesis, starting
from the genetic information in DNA, through transcription to produce messenger
RNA, and translation of mRNA to a polypeptide. We also consider
post-translational processing, and how this is involved in transporting the
protein to appropriate parts of cells; and the degradation of proteins.
