RNA polymerase can copy genes for proteins in more than one
27
region of the DNA. This can be compared to a number of peo-
ple reading the different pages of the same book at the same
time. Performing this exceedingly complex multi-stage process
in several places simultaneously without a single mistake re-
quires enormous care and competence. How many tasks can a
rational, conscious human handle at the same time? How many
products can he supervise concurrently? Answer these ques-
tions, and you can more clearly understand the abilities pos-
sessed by a mRNA molecule.
Additional Structures that the
Ribosome Needs
We have already seen that the ribosomes are like factories.
However, in order for the production in this factory to continue
accurately and swiftly, other proteins are needed. After the mR-
NA that carries the code of the amino acids attaches to the
small subunit of the ribosome, the tRNAs carrying the corre-
sponding amino acids attach to site A of the ribosome with the
help of a molecule called Ef-Tu. Following various control
processes, a bond will be formed with the amino acid on the tR-
NA in site P. If an error is detected in these processes, the faulty
amino acid will be discarded. With the help of another protein
called Ef-G, the upper part of the ribosome will be moved one
step further, followed by the lower part also moving one step
further. In this way, tRNAs in the sections P and A will be
moved to sections E and P. As a result, space will be cleared
both for the next amino acid specified by the mRNA, and the
tRNA that carries that specific amino acid.
