The protein synthesis can be divided in three phases:initiation, elongation and termination.
a. Describe the initiation phase as it takes place inbacteria.
b. The initiation phase in pro- and eukaryotes begindifferently, when it concern the recognition of mRNA, describethese differences.
c. tRNA transport amino acids to the ribosome. Which part of thetRNA molecule form a covalent link to the amino acid? And what isthe name for the general class of enzymes that catalyse theformation of a covalent bond between tRNA and aminoacids?
d. Describe the mechanism which ensure that only the amino acidthreonine is attached to threonyl-tRNA.
