Discuss all the different ways and mechanisms that eukaryotes use to regulate gene expression.
There are four levels of regulation of gene expression in eukaryotes -
1. Transcriptional control
Transcription of the process of formation of RNA using DNA template and DNA dependent RNA polymerase as an enzyme. This is regulated because in the error containing RNA which is formed during this process is either corrected or degraded.
2. RNA processing
RNA processing in the method in which the premature RNA is converted into primary transcript. Premature RNA as formed by transcription. Primary transcript is formed by capping, tailing and splicing of premature RNA.
This regulation is important because any primary transcript containing any error prone capping sequence or tailing sequence or is formed abnormally after splicing is degraded.
3. Transport of RNA from nucleus to cytoplasm
This regulation is important so that RNA is transported from nucleus to cytoplasm without being degraded by nucleases. Any abnormal RNA is degraded by nucleases.
4. Translational control
Translation of the process of formation of proteins using RNA as a template. This control is important so that any abnormal sequence of amino acid which is formed and any abnormal three-dimensional protein which is formed after post translational modification is degraded.

Discuss all the different ways and mechanisms that eukaryotes use to regulate gene expression.
Which of the following mechanisms to regulate gene expression are observed in eukaryotes, but are not generally observed in prokaryotes? Choose all that apply. Genes are grouped into operons, which allows transcriptional regulation to turn them all on together. RNA silencing selectively targets mRNA and destroys it to prevent further translation. Proteins can be activated or deactivated as a form of post-translational regulation. Epigenetic regulation can open or condense sectiosn of a chromosome, regulating which genes are transcribed. Regulatory proteins...
name TWO mechanisms of control of gene expression that are only used by eukaryotes and discuss why each of those mechanisms wouldn’t be possible in prokaryotes.
Each answer box represents a mechanism by which eukaryotes can regulate gene expression. Determine which of the five mechanisms each example represents. Not all examples will be used.
Both prokaryotes and eukaryotes regulate gene expression, turning genes on and off in response to various cues. Which of the following mechanisms is common to both types of cells? Choose all that apply. alternative splicing of mRNA opening or condensing chromatin transcriptional regulation post-translational regulation
Select all of the following ways that gene expression is regulated in eukaryotes.
Regulation of Gene Expression in Eukaryotes In all organisms, certain genes are expressed at any given time while other genes are not. Both prokaryotes and eukaryotes regulate gene expression at the transcription stage. However the greater complexity of eukaryotic cells makes it possible for gene expression to be regulated at many other stages as well. The diagram below shows different stages at which gene expression may be regulated in eukaryotes. nucleus chro modifica anscription RNA processing cytoplasm degradation protein processing...
Detailed explanation plz. 4. In class, we discussed that regulation of gene expression in eukaryotes and prokaryotes have some similarities and some differences. I want you to focus on what's different between these two type of cells: name TWO mechanisms of control of gene expression that are only used by eukaryotes and discuss why each of those mechanisms wouldn't be possible in prokaryotes.
