Chapter 15, Problem 8TYK
Summary Introduction
Introduction:
Transposable elements (TEs) are the sequences of DNA that can move from one location to other. This movement is called transposition. It remains involved in the genetic recombination.

A researcher has identified a mutant strain of yeast whose histones are unable to be acetylated. Which of the following is the MOST reasonable prediction for how the phenotype of this mutant yeast will differ from the phenotype of yeast cells with acetylated histones?
A. The mutant will grow more rapidly.
B. The mutant will grow much more slowly.
C. The mutant will show decreased levels of gene expression.
D. The mutant will show increased levels of gene expression.
A cell has a mutated mediator protein.
a) How will this affect transcription of genes? (circle an answer below)
No transcription
Weak transcription will occur
Strong transcription will occur
b) Why? Describe your choice above
A gene, which we will call gene C, can be epigenetically modified in such a way that its expression in some cells is permanently silenced. Describe how you could conduct cell-fusion experiments to determine if a cis- or a trans-epigenetic mechanism is responsible for maintaining the silencing of gene C.

- Which of the following mutations could be appropriately describedas a position effect?A. A point mutation at the –10 position in the promoter regionprevents transcription. B. A translocation places the coding sequence for a muscle-specificgene next to an enhancer that is turned on in nerve cells.C. An inversion flips a gene from the long arm of chromosome 17(which is euchromatic) to the short arm (which isheterochromatic).arrow_forwardThere is Hyaluronic acid synthesis occuring in Group X Strep and it is controlled by an operon with 3 genes, called hasXYZ. Based on the 3-line diagram model, a. How many ribosome binding sites are there for the protein? b. How many promoters are there for the genes? c. How many start codons are there for the protein? d.

Oncogenes are mutant genes that are overexpressed and cause cancer. New gene therapies are aimed at silencing oncogenes by producing antisense RNA that recognizes the mRNAtranscribed from oncogenes. Based on your understanding of antisense RNA , explain how this strategy would prevent the growth of cancer cells.arrow_forward
- The insertion of transposable elements into genes can alter the normal pattern of expression. In the following situations, describe the possible consequences on gene expression.a. A LINE inserts into an enhancer of a human gene. b. A transposable element contains a binding site for a transcriptional repressor and inserts adjacent to a promoter. c. An Alu element inserts into the 3′ splice (AG) site of an intron in a human gene. d. A Ds element that was inserted into the exon of a maize gene excises imperfectly and leaves three base pairs behind in the exon. e. Another excision by that same Ds element leaves two base pairs behind in the exon. f. A Ds element that was inserted into the middle of an intron excises imperfectly and leaves five base pairs behind in the intron.arrow_forwardA geneticist uses a generic engineering approach to mutate the TATA-building protein (TBP) of a murine cell line that ordinarily produces high amounts of the LNS protein. The mutation prevents the binging of the TBP to the TATA box.

In the previous problem you proposed a model for how this gene could be regulated. Suppose that you carry out an experiment to test your model. To do this you cut out the regulatory sequences upstream of the gene and fuse it to a gene for green fluorescent protein (GFP). Now you can visually observe when the gene is activated. You insert this engineered gene into a host cell and look for GFP expression. You discover some mutants that have different expression levels of GFP and call them GFP1- and GFP2-. The expression levels of GFP are given below. Cell GFP expression Wild type 100 GFP1- 50 GFP2- 0 Propose an explanation for these results based on your model.
