Looking at the diagram of transcription in eukaryotes and using the
information provided, how could the expression of lactase RNA be
turned on and off by transcription factors, activators and
repressors?
Styles Font Paragraph Activators bind to genes at Rapressors bind to genes seauences and at shaoser sequences and The expression of RNA in eukaryotes is initiated by the binding of basal transcription factors to the promoter sequence of a gene. This leads to the recruitment of RNA polymerase to...

QUESTION 9 Regulation of gene expression by eukaryotes is more complicated that in prokaryotes. The promoter region contains proximal regulatory sequences that are called _regulatory elements. These proximal regulatory elements bind trans-acting proteins that are called __factors.

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...

Some simple eukaryotic genes can be transcribed and translated by prokaryotes like E. coli. However, some eukaryotic genes cannot be expressed by prokaryotes. Which of the following might be a reason for this failure? A. Prokaryotes are not able to cut out the introns nor are they able to O splice the exons together from the eukaryotic gene. B. the prokaryotic genetic code is sometimes different from eukaryotic code. C. Eukaryotic genes often have unique nucleotide bases which are not...

QUESTION2 Which of the following statements is TRUE? O DNADNA hybrids and RNADNA hybrids are always antiparallel O DNA is replicated using the template strand as the template but RNA is transcribed using the sense (or coding) strand as the template. O Both DNA and RNA polymerization require a primer O Introns get spliced out of DNA and out of pre-mRNA QUESTION 3 0. Which of the following statements is FALSE? O Only Eukaryote genes have an A/T rich core...

1. trans-acting factors are able to regulate target genes from any chromosome, whereas cis-acting elements can only regulate genes located in the same chromosome. a. True only in operons. In Eukaryotic systems, trans-acting factors only regulate genes in the same chromosome. b. True only in Eukaryotes. Prokaryotes don’t have cis-acting elements. c. True for any organism. d. False. The statement is erroneous 2. Unlike activators, repressors never affect chromatin structure. Repressors inhibit transcription only by binding to the binding sites...

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...
