#Unit 3. Fundamental Processes

There are two major steps to start translation

1. Activation of amino acids,

2. Assembly of ribosomes.

#Unit 3. Fundamental Processes

The tRNAs provide the physical interface between the amino acids being added to the growing polypeptide chain and the codons in the mRNA.

#Unit 3. Fundamental Processes

Aminoacyl-tRNA synthetases couple amino acids to specific tRNAs that recognize the appropriate codon(s).

#Unit 3. Fundamental Processes

The ribosome coordinates the correct recognition of the mRNA by each tRNA and catalyzes peptide-bond formation between the growing polypeptide chain and the amino acid attached to the selected tRNA.
