, As long as we know the amino acids, we can predict the primary structure of the protein
Bc transcripts are red in triplicate (codons), tRNA can find codons
64 potential combinations of codons → redundancies, multiple triplicates code for the
same thing (helps avoid mutation even if there’s an accidental code change)
Stop codons don’t have a complementary anticodon, indicates termination of translation
AUG (methionine / start) - all initial transcripts start with AUG, but not all proteins start
with this
, Bottom of ribosome scans transcript looking for the AUG, clamps down into a sandwich,
starts translation
Methionine sits in P site, tRNA (which has anticodons and methionine) starts translation,
Leucine goes into A-site (“empty site”), Leucine moves into P site so that the next thing
can go in the A-site
, More than one ribosome can attach to a transcript at the same time
Once the ribosome reaches stop codon, the whole complex gets destabilized, the
ribosome falls apart, and releases the new peptide chain to become a new protein
