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.
Homework Answers
In eukaryotes, post-transcriptional and post-translational control are possible but not for the prokaryotes.
In eukaryotes, transcription happens in the nucleus and after transcription, the nascent mRNA undergoes several mRNA processing even like 5' capping, splicing, alternative splicing and 3' tailing which are not possible for prokaryotes as they lack this complete mRNA modification system and co-transcriptional translation happens in prokaryotes.
In eukaryotes, the synthesized protein undergoes further processing inside the ER and Golgi bodies if needed but this system is not present in prokaryotic cells.
Moreover, the eukaryotic cells also regulates gene expression by histone modification which is not observed in the prokaryotes.

Part 1. Eukaryotes use at least two distinct mechanisms to control gene expression by altering the structure of chromatin around a particular gene. One of these mechanisms is the covalent modification of histones to switch DNA between an open and closed confirmation. A second mechanism is the covalent modification of DNA (typically on cytosines) by methylation. A. Describe a type of histone modification and explain what effect is has on chromatin, and how that effect is achieved. a. One type...

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...

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...

Coordinate regulation of gene expression is important both in bacteria and eukaryotes. Operons are used to co-ordinate gene expression in bacteria but NOT eukaryotes. Explain why operons strategy does not work in eukaryotes.

Transcriptional control of gene regulation is common in both prokaryotes and eukaryotes. Which of the following is not true? Both prokaryotes and eukaryotes: A. exhibit both positive and negative control. B. have repressors that impact expression. C. often requires interactions with DNA that is not proximal to structural genes. D. have genes that are closely related in function located proximally on a chromosome
