B. Alternative splicing.
C. Export of mRNA from the nucleus.
D. Transcriptional repression.
E. Destruction of mRNA
Q2) Trans-acting regulators of gene expression include?
A. promoters.
B. histone deacetylases
C. introns
D. silencers
E. the TATA box.
Q3) Gene regulation in eukaryotes often involves which of the following, which are not also used by prokaryotes?
A.RNA polymerase
B.Transcription factors
C.Histone modification
D.Promoters
E.Coupled transcription and translation
Homework Answers
Answer 1 change to DNA sequence is not involve in gene expression as change to DNA sequence means mutation, so it is not involved in gene expression.
Answers 2 histones deactylases is the trans acting regulator.
Answer. 3 histone modification is the gene regulation in eukaryotes

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...

The main differences in gene expression between prokaryotes and eukaryotes result from the presence of a nucleus in eukaryotes. Which of the following is FALSE when comparing transcription between prokaryotes and eukaryotes? Prokaryotic mRNA goes through multiple modifications before translation Eukaryotic genes have introns that need to be removed before translation Prokaryotic mRNA can be translated while it is still being transcribed Eukaryotic mRNA needs a 'cap and a 3'tall to prevent its degradation 0/2 pts Question 45 Lets play...

Regulation of Gene Expression in Eukaryotes In eukaryotes, the Central Dogma of Genetics can be expanded to include post-transcriptional processing and post-translational processing, thus the Dogma becomes: Replication - Transcription Post-transcriptional Processing -Translation - Post-translational Processing - Functional Protein - Expressed Trait. This is the flow of information from the genetic material to the actual physical, chemical or behavioral trait in an organism. Of course, some traits are controlled by multiple genes and some also have an environmental component. At...

Which of the following is not true regarding regulation of gene expression in eukaryotes? In eukaryotic cells, transcriptional activators often work by recruiting the transcriptional macinery to gene promoters DNA methylation is an example of an epigenetic mark that can be inherited Acetylation of histones can result in a more open chromatin structure to allow transcription to occur Different genes can be turned off or on between different organs or stages of development Transcription factor DNA sequences are bound by...
