Translation: elongation.
The
anticodon
of an incoming
tRNA
base-pairs with the complementary
codon
in the
A
site.
A
peptide
bond is formed between the new
amino acid
in the
A
site and the growing polypeptide in the
P
site.
The
ribosome
translocates the
tRNA
in the
A
site to the
P
site.
The empty
tRNA
in the
P
site is moved to the
E
site and released. The
mRNA
moves the next
codon
into the
A
site.
Translation: elongation.
