How does the structure of tRNA molecule enable it to carry out its function?

I have anticodon can pair with codon on mRNA. - that's about all I got!

and How does the structure of RNA molecule enable it to carry out its function?

Thank you Thank you Thank you Thank you :biggrin:

Relaxation of normal base pairing rules between the 1st position of the anticodon and the last of the codon (technically called 'wobble') - means the number of tRNA molecules required to encode all (almost all) possible combinaions of codons is reduced, without detriment to the accuracy of the process. How about the fact that tRNAs can form amino-acyl tRNAs: they get amino acids attached to a CCA (or something like that) sequence at one end.

Think - what is the function of RNA? Is there one?
