Translation overview

 

The genetic code

 

Are there 61 different tRNAs?

If not, how are all 61 of the codons serviced?

 

What would be the minimal number of tRNAs needed to service Ile codons?

 

Initiation of translation

 

How do the ribosomes know where to start translation?

 

 

What is the protein sequence coded for by the mRNA below?
