Chapter 16.1, Problem 3LO
Summary Introduction
To list: The differences between control of gene expression in prokaryotes and eukaryotes.
Introduction: Gene expression is the process by which genetic information of a gene is used to form a functional gene product. The expression of gene includes the following process like transcription, RNA splicing, translation and post translational modification (PTM). The control of gene expression is important for prokaryotic and eukaryotic organisms. This may either inhibit or stimulate gene expression.

Describe and give an example of each of the following levels of gene expression control in eukaryotes:
a) epigenetic control
b) transcriptional control
c) post-transcriptional control
d) translational control
e) post-translational control
The most common type of regulation of gene expression occurs at the level of transcription. Name other types of gene regulation for gene expression in eukaryotic cells. Name types of gene regulation unique to eukaryotic cells versus prokaryotic cells.

No transcript will be made, because eukaryotic DNA cannot be transcribed by prokaryotic RNA polymerase. The protein will be made but will not function, because prokaryotes cannot remove introns. The protein will not be made, because prokaryotes lack the ribosomes necessary for translation.
