what are two components that are present in both eukaryotic/prokaryotic gene regulation, and what is one that is specific to eukaryotic only?

Expert Solution

A) Components that are present in both eukaryotic/prokaryotic gene regulation are :

Both prokaryotic and eukaryotic gene expression require the participation of promoters and regulatory elements.

RNA polymerase binds to promoters in DNA to initiate transcription.

Promoters contain, or have near them, binding sites for transcription factors that can help to recruit or repel RNA polymerase.

Prokaryotes has activator and repressor proteins that act on operators.

Eukaryotes has activator proteins act on enhancer DNA sequences and repressor proteins act on silencer DNA sequences.

B) Components that are specific to eukaryotic only are :

Components that are specific to eukaryotic only are mRNA processing like capping, splicing and adding ply adenine tail, and then have a special mechanism to transport the processed mature mRNA to the cytoplasm from the nucleus.

Prokaryotes do not have introns. But in eukaryotics because introns are present, so splicing of introns and joining of exons is needed.
