In Termination- finished polypeptide chain is released.It
begins when a stop codon (UAG,UAA,UGA) enters the
ribosome,triggering a series of events that seperates the chain
from its tRNA and allow it to drift out of ribosome.
Determine whether each event occurs during initiation,
elongation, or termination. Initiation Elongation Termination
In prokaryotes, the shine-dalgarno sequence pairs with rRna,
Translocation occurs,
In Ecoli, EF-Tu delivers an aminoacyl-tRNA to the ribosome,
In Ecoli, mRNA binds to the 30S ribosomal subunit,
Initiator tRNA enters the P site,
In Ecoli, EF-Tu hydrolyzes GTP,
In Ecoli RF1 recognizes UAG and binds at the A site

Bacterial translation involves a lot of factors and steps
(initiation, elongation, termination, recycling, etc). Explain the
steps involved in a cycle of bacterial translation elongation.
Specify at which steps there is an energetic requirement (e.g. ATP
or GTP hydrolysis). How many ATP and GTP molecules are consumed per
one cycle of bacterial translation elongation assuming that there
are no mistakes?
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...

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...
