What is the ribosome actually do? I know it rolls across an mRNA but what is its function?
How do aminoacids connect to the appropriate tRNAs?
Thanks!

You could start here:

Thanks I have read the Wikipedia articles already but can't find the answer to my questions.
I will watch the video later but I don't think it will have the information I need.
As for the ribosome I want to know which particular reaction it catalyses.
As for tRNA, how they bind the specific amino acid.

This one might help...
There is a family of separate enzymes (each as complex as t-RNA) which ensures that exactly the right amino acid gets attached to the right t-RNA.

Humans use 20 amino acids, so there are 20 of these enzymes, see:

That's what I needed thanks.
As for the ribosome? Does it catalyse the binding of tRNAs to mRNAs? The formation of peptide bonds? Anything else?
What is its exact role?
