What is a more radical change
translation
do codes overlap
no
Ribosomes with large and small subunits, are what
aggregates of rRNAs and proteins
Prokaryotic initiation of translation uses what sequence
the shine-dalgarno sequence
what does the shine dalgarno sequence do
its a sequence at the 5’ end of the mRNA upstream of the start codon, which pairs wirh rRNA and positions the mRNA properly
Initiation Factor proteins in prokaryotes
A U G
what is the eukaryotic translation initiation factor
eIF
EF-Tu def
elongation factor, brings next amnoacyl tRNA to the A site
EF-G def
moves assembly to expose next codon
Peptidyl transferase def
catalyzes peptide bond formation
is termination of translation similar in pro and euk
yes
release factor def
a protein that pairs a tripeptide rather than an anticodon with the stop codon; its bonding causes dissociation of the whole assembly
tRNAs def
work as adapters or translators to connect that language of nucleic acid and amino acids
what two things need the tRNA
protein and RNA
Acceptor end def
binds amino acid
