Document Summary
Looking ahead ribosomes with gene-specific activity (chapter 13) The enriched expression of specific ribosome proteins (rps) in different tissues may confer translational specificity to distinct classes of mrnas. They arise (cid:498)spontaneously(cid:499) all the time as a result of an error during dna synthesis. Incorporation of raise isoforms of the four bases that have been altered in terms of their base pairing properties. The nitrogenous bases of dna exist in two isoforms. Demonstrates the favorite atom chemical vs. the one that is considered more rare. These rare forms have (cid:498)altered(cid:499) base pairing properties. (fig. Incorporation of a rare isoform during dna replication can lead to a change in the. Dna sequence: somatic mutations: may affect the individual in which they occur in dramatic ways but it will not be passed on. Most of the time we are not sure whether the effect will take place or not. Generally they have no consequence to genes only those in terms of proteins will.
