QUESTION 14Which of the following statements about bacterial translation is FALSE?O A. The arrangement of key sites within the ribosome is in the order E, P, A, for exit, peptidyl, and aminoacylO B. Steps in translation initiation, elongation, and termination are moved forward in an irreversiblemechanical process, almost like turning a crank, that relies on the hydrolysis and exchange of GTP.O C. The first step in translation is the binding of the 30S RNA subunit to the Shine Delgarno sequence,together with IF-1 and IF-3.O D. Termination of translation requires a set of release factors RF1/2, RF3, and RRF which help coordinateevents following the recognition of a stop codon by one of the three stop codon tRNASO E. A polysome consists of multiple ribosomes reading the same MRNA at once. Those positioned towardsthe end of the mRNA have translated more of the protein than the ribosomes positioned at thebeginning.

A) The ribosomes have the two subunits of the rRNA and the proteins, a large subunit with the three active sites (E,P,A )vwhich are critical for the catalytic activity of the ribosmes. B) Protein synthesis is facilitated by the several catalytic proteins which includes the initiation, elongation and the termination factors and the GTP .GTP is a molecule that releases energy when converted into GDP C) the mRNA binding site of the mRNA is called the Shine Dalgarno Sequence that lies appr. 10 nucleotides ahead of the initiation codon.Protein synthesis initiation is itself triggered by the initiation factors such as the IF1,IF2 and IF3 , including the mRNA, ribosmes and the tRNAD) There are three release factors for The recognition of the stop codons ie RF1, RF2 and RF3 . E)The mRNA molecules are translated simultaneously by many ribosomes increasing the rate of protein synthesis. The complex of mRNA and ribosmes is called polyribosomes or the polysomes. Polyribosomes positioned at the 3' end have the longer protein than those placed at the begining ie 5' end . The ribosomes are attached at the 5' end and proceeds in the 3' direction ,moreover the polypeptide becomes longer as the ribosmes move along the mRNA while the transcription takes place at the 3' end So here all the answered are correct except the option c
