Question
Chapter 19, Problem 3TYK
Summary Introduction
To review:
In Eukaryotes, only certain genes are allowed to be expressed in different types of cells.
Introduction:
Eukaryotes are made up of a large amount of DNA (deoxyribonucleic acid). The DNA sequence remains the same in an individual. Regulation of gene expression is a complex phenomenon. There are a number of regulatory DNA sequences, which promote and suppress gene expression during transcription.

- Compare the control of gene regulation in eukaryotes and prokaryotes at the level of initiation of transcription. How do the regulatory mechanisms work? What are the similarities and differences in these two types of organisms in terms of the specific components of the regulatory mechanisms? Address how the differences or similarities relate to the biological context of the control of gene expression.arrow_forwardProvide a detailed description of gene expression and control in prokaryotes.

- Regarding eukaryotic genes, it is correct to state that: * A) Distal enhancer-like elements decrease the intensity of gene transcription activation B)Mutations in intronic regions of a gene can alter the levels of its corresponding protein C)They are regulated only by promoter regions, being activated or repressed by the presence of transcription factors D)The junctions of exons and introns are recognized by splicing factors, which ensure the production of the same mRNA regardless of cell type.

A mutated eukaryotic cell contains an altered base-pair in an intron of gene X. Which would be the most likely effect of this mutation on the biomolecules in the cell? The amount of pre-mRNA transcribed from gene X would be less than normal. The amount of functional protein corresponding to gene X would be less than normal. The ability of snRNAs to form a spliceosome would be diminished. The breakdown of mature mRNA corresponding to gene X would be fasterarrow_forward
- Why might repression of a eukaryotic gene by an RNA be more efficient than repression by a protein repressor? O Protein repressors only prevent the synthesis of a single splice variant of a gene. O RNA repressors bind directly to nucleotide sequences in genes, preventing their transcription. O Protein repressors are inherently unstable, so they degrade quickly and do not completely repress genes. O Synthesis of RNA repressors is less energetically costly than that of protein repressors.arrow_forwardMicrobiologists describe the processes of transcription and translation as “coupled” in bacteria. This term indicates that bacterial mRNA can be undergoing transcription at the same moment it is also undergoing translation. How is coupling possible in bacteria? Is coupling of transcription and translation possible in single-celled eukaryotes, such as yeast? Why or why not?arrow_forwardSearching the yeast Saccharomyces cerevisiae genome, researchers found approximately 4,000 DNA sites with a sequence which could potentially bind the yeast transcription factor GAL4. GAL4 activates the transcription of galactose genes. Yet there are only 10 GAL4-binding sites which control the genes necessary for galactose metabolism. The GAL4 binding sequence is CGGAT#AGAAGC*GCCG, where # is T, C or G, and * is C or T. In one chromatin immunoprecipitation experiment (ChIP), yeast growing on galactose were lysed, and subjected to cross-linking reagents which cross-linked transcription factors and activators to DNA. Next the DNA was sheared into small fragments, and antibodies to GAL4 were added. These antibodies coprecipitated the GAL4 and the DNA it was cross-linked to. The cross-linking was then chemically reversed, and the DNA was isolated, cloned into a library of plasmids and sequenced. Results showed that only 10 different DNA sequences had GAL4 bound. Since the…arrow_forward
