A gene-regulation strategy that is unique to eukaryotic cells is __________. See Section 19.1 ( page 380) .
A. transcriptional regulation
B. mRNA processing
C. post-translational regulation
D. Translational regulation
level of regulation UNIQUE to Eukaryotes is RNA Processing
RNA Processing
In eukaryotes, the changes that a primary RNA transcript undergoes
to become a mature RNA molecule. For pre-mRNA it includes the
addition of a 5' cap and poly(A) tail and splicing to remove
introns
the steps required to produce a mature, processed mRNA from a
primary RNA transcript
So answer is B
A gene-regulation strategy that is unique to eukaryotic cells is __________. See Section 19.1 ( page...
This short RNA (miRNA) is found in eukaryotic cells. miRNAs are post-transcriptional regulators that bind to complementary sequences on target mRNAs, resulting in enhancement of mRNA degradation by nucleases and/or _________. For the study of gene functions, artificial introduction of miRNA (siRNA) is performed to cells or animals. This experimental technique is called gene silencing and or _________, compared to the gene-deleting transgenic techniques. Select one: a. transcriptional repression ;;;; Knock-Down b. translational repression ;;;; Knock-Down c. transcriptional repression ;;;;...

What is the difference in gene regulation between eukaryotic and prokaryotic cells?
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...
Please briefly explain the Regulation of Gene Expression in Eukaryotes at various levels (Please explain EACH): - Chromatin Structure/ Epigenetics - Transcriptional control - Processing and Stability of mRNA - Translational Control - Posttranslational control of protein function - Eliminating the Protein
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
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...
In eukaryotes, post-transcriptional control of gene regulation may involve Question 19 options: a. alternative mRNA splicing. b. alternative mRNA splicing, control of nuclear export of mRNAs to the cytoplasm, and differential mRNA degradation. c. control of nuclear export of mRNAs to the cytoplasm. d. differential mRNA degradation.
