Document Summary

Note: if poly- a tails are too short, there will be no translation that occurs: splicing, snrnps: small nuclear ribonucleoprotein particles.

Inosine (found in the codon) can bind to uracil, cytosine, and adenine (not. In yellow: all encoded by the same gene rna pol i: 5s is encoded by rna pol iii, the 4 different rrnas (after being encoded by rna pol) are ready to complex w/ ribosomal proteins. Note: rrnas within the large subunit catalyze peptide bond formation; ribosomes build polypeptides one amino acid at a time.
