Compare 3D Structure of Two tRNA Molecules

Yeast Met-tRNA
Yeast Phe-tRNA

Look at the Bacillus subtilisRNase 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. Met-tRNA Phe-tRNA.
