Compare 3D Structure of Two tRNA Molecules
Yeast Met-tRNA
Yeast Phe-tRNA
Look at the
Bacillus subtilis
RNase P
3D structure.
These two tRNA molecules carry two different amino acids to the A site in a ribosome as it synthesizes a new protein. The one one left carries a
methionine
and the one on the rightcarries a
phenylalanine
.
Reset Met-tRNA
and Phe-tRNA
.
Look at the overall structure.
Met-tRNA and
Phe-tRNA. Do they look similar overall?
Are the two identical? Would you expect them to be identical?
Let's look at the anti-codons and see if we can detect their differences.
