What does tRNA stand for?
Transfer RNA
What are the characteristics of tRNA?
-short
,
single stranded molecule
-forms a
clover leaf shape
What is the function of tRNA?
Transports amino acids
to the
ribosome
so that
proteins
can be
synthesised
in
translation
What is the structure of tRNA?
-each tRNA molecule has an
amino acid attachment site
ending in
CCA
-at the
opposite end
of the molecule there is an
anticodon
(a
triplet
of
bases
)
How does tRNA bind to mRNA in the ribosome?
The
anticodon
bases form a
complex
with
complementary
bases on the mRNA molecule (
codon
).
