- Shine-Dalgarno sequence present in the prokaryotic mRNA plays a role in initiation of translation. In eukaryotes a Shine-Dalgarno like sequence is present but does not play an important role in initiation of translation.
- We often try to express a eukaryotic gene in a prokaryote. For example : expressing insulin gene in E.Coli.
My question : If eukaryotes do not have the shine dalgarno sequence , then how can a eukaryotic protein be expressed in a prokaryote ? (I am especially interested in knowing about this in case of cDNA expression)
