Question
Which statements regarding translation are correct? (There may be more than one answer).
EF-Tu moves the mRNA by one codon
EF-G delivers aa-tRNAs to the ribosome
Translation initiation occurs by 70S riboosomes binding to mRNAs with fMet-tRNA
Translocation refers to the chemical step of peptide bond formation
RRF functions to cleave off the peptide chain from the P-site tRNA
IF3 is released after the 30S subunit binds mRNA and the fMet-tRNA sits in the P-site; this allows the 50S subunit to bind

Explanation / Answer
Option - no elongation Tu factor does not move on the m RNA it just bind to the ribosomes and attached the t RNA and then release. wrong
Option 2 - this option is correct elongation factor G have amino acid latest t RNA which is transferred to the ribosomes complementary anticodon to the mRNA.
option 3- ribosome binds with the m RNA and the initiation of translation occur with the formyl methionine aminoacylated tRNA. so this option is correct.
Option 4 yes correct.
option 5 - ribosome releasing factor have work to release ribosome and peptide from ribosomes.
correct.
option 6- yes this option is also connect
