Question

Compare and contrast the difference between prokaryotic and eukaryotic protein synthesis.

Answer 1

Eukaryotic protein synthesis	Prokaryotic Protein Synthesis
m RNA molecules are monocistronic	mRNA molecules are polycistronic
Protein Synthesis occurs in the cytoplasm	Protein Synthesis begins even before the transcription of mRNA molecuke is completed
Most of the genes have introns	Do not have introns.
Primary mRNA transcript undergoes Processing and splicing	Splicing of mRNA transcript does not occur
mRNA molecules are modified by 5'G cap	No such cap is formed
A polyA tail is formed at the 3' end of mRNA	No polyA tail is added
First amino acid methionine entering ribosome is not formylated	First amino acid methionine entering ribosome is formylated
9 initiation factors are involved in pre initiation complex formation	2 initiation factors are involved in pre initiation complex formation
