The protein synthesis can be divided in three phases: initiation, elongation and termination.

a. Describe the initiation phase as it takes place in bacteria.

b. The initiation phase in pro- and eukaryotes begin differently, when it concern the recognition of mRNA, describe these differences.

c. tRNA transport amino acids to the ribosome. Which part of the tRNA molecule form a covalent link to the amino acid? And what is the name for the general class of enzymes that catalyse the formation of a covalent bond between tRNA and aminoacids?

d. Describe the mechanism which ensure that only the amino acid threonine is attached to threonyl-tRNA.

Translation can be considered to have three phases or steps: initiation, protein synthesis, and termination. Please give a detailed summary of the factors and molecules involved with each step and, where appropriate, compare/contrast the differences between prokaryotic and eukaryotic translation.

Determine whether each of the events involved in protein synthesis occurs in initiation, elongation, or termination.

Determine whether each of the events involved in protein synthesis occurs in initiation, elongation, or termination. Initiation Elongation Termination Answer Bank The small and large ribosomal subunits combine to form an initiation complex. The tRNA, mRNA, and new protein are released. The small ribosomal subunit attaches to an mRNA molecule. The ribosome moves down the mRNA strand to the next codon. An initial tRNA molecule pairs with the AUG codon of the mRNA molecule. Amino acids are transferred from tRNA molecules to the growing peptide chain. The ribosome reaches...
