Process of translation
Ribosome attaches to 2
codons
on the mRNA
tRNA
anticodons
bind to complementary
codons
forming
hydrogen bonds
peptide
bond forms between
amino acids
at the top of the tRNA
Active process -> needs
ATP
to activate amino acids
Ribosomes moves along one codon
First tRNA leaves to bind to a
new amino acid
Third tRNA binds to the
complementary third codon
Repeat steps 3-7 until
STOP codon
has been reached and the
release factor
binds
Polysomes
are when several ribosomes work on the same
mRNA
molecule
