A tRNA with it's anti-codon and attachment
Transfer RNA molecules, like
mRNA
and other types of RNA, are
transcribed
from DNA templates within the nucleus of a eukaryotic cell. Like
mRNA, tRNA must travel from the nucleus to the cytoplasm, where the
translation
occurs. Each tRNA molecule can then be used repeatedly, picking up its designated
amino acid
in the cytosol, depositing this cargo at the
ribosome
and leaving the ribosome to pick up another load. The structure of
a tRNA molecule fits its function as a shuttle for a certain, specific
amino acid.
This site contains links to other pages created by us, the students, as well as links to the University of Arizona Biology Dept. At the UofA bio site, it is here where you will be able to find some problem sets on the material covered, as well as some materials that were presented in class during this past week. If you have any trouble with the problems, don't worry. It's a college course, however most of it should be accesible. If you REALLY like this stuff and want to understand even more (hey, why not?), try the tutorial at the UofA website. It'll provide some insight for the more obscure problems.
