Protein in synthesis in initiated by initiation factors . There are three initiation factors in prokaryotes like IF1, IF2 , IF3 similarly eukaryotes there are nine initiation factors like elF1 , elF2 , elF3 etc .
Ribosomes are scattered in cytoplasm as separated units .That means both the sub units are detached from each other .
elF2 or elF3 gets attached to the smaller subunits are assembled from 80s ribosome in eukaryotes and 70s ribosome in prokaryotes .
The larger subunit of ribosome has 3 rites
These are p- site peptidyl site
A site - aminoacyl site and
E site - exit site
The first amino acid tRNA complex gets attached to the p site i.e. AUG known as initiation codon .
Th first amino acid formed in the process of translation is fermylated methionine incase of prokaryotes where as methionine in eukaryotes .
