Question
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.

Which ONE of the following is TRUE concerning the so‐called Philadelphia chromosome?
Select one:
A.It results in loss of BCR serine‐threonine kinase activity
B.It leads to generation of a fusion protein with constitutively active tyrosine kinase activity
C.It results from a t(8;21) translocation
D.Overexpression of the ABL1 gene results from a translocation that brings a strong gene promoter close to the ABL1 gene
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).
Mutations in the CFTR gene result in cystic fibrosis in humans, a conditions in which abnormal secretions are present in the lungs, pancreas, and sweat glands. The gene was mapped to a 500-kb region on chromosome 7 containing 3 candidate genes.
a)Using your knowledge of the disease symptoms, how would you distinguish between the candidate genes to decide which is most likely to encode the CFTR gene?
b)How would you prove that your chosen candidate is the CFTR gene?

- Which of the following is an explanation for how there can be differential gene expression throughout a multicellular organism? A) There are unique sets of genes present in the different tissues of the organisms B) Some tissues have histones, while other cells do not use histones C) There are unique combinations of transcription factors in different tissues of the organism D) Different tissues throughout the organism use different genetic coding rules .arrow_forwardWhat does it mean for a transposable element to be effectively “dead”? A. The transposable elements are “dead” because they are only found in non-coding regions and therefore do not interfere with phenotypic expression. B. The transposable elements are “dead” because they are no longer able to undergo transposition and move to another region of the genome. C. The transposable elements are “dead” because they do cause disease despite their presence. D. The transposable elements are “dead” because they occur only in somatic cells and therefore are not heritable.arrow_forwardIf a mutation occurred in a control element sequence associated with a particular gene, which of the following would be a likely consequence of this? A. This mutation is not likely to affect the expression of the associated gene, because RNA polymerase does not bind to control elements. B. This will likely affect the expression of the associated gene because it will loosen the coiling of chromatin at this site. C. The expression of the associated gene will be affected because this change will result in a nonsense mutation. D. This mutation is not likely to affect the expression of the associated gene, since control elements are noncoding sequences. E. The associated gene's expression would likely be affected, since this mutation would change the ability of at least one transcription factor to bind.arrow_forward
- Which of the following is true of CpG islands? a. They are methylated near promoters of actively transcribed genes. b. They are unmethylated near promoters of actively transcribed genes. c. Acetylation of CpG islands leads to repression of transcription. d. CpG islands code for RNA molecules that activate transcription.arrow_forwardSickle cell disease is caused by a substitution in the beta globin gene. As a result, one amino acid is different in the mutant protein. Which of the following region is likely to be affected in the sickle cell allele? A. The promoter region B. The 5' UTR region C. The coding region D. The 3' UTRarrow_forwardWhich of the following best represents the central dogma of geneexpression?a. During transcription, DNA codes for polypeptides.b. During transcription, DNA codes for mRNA, which codes forpolypeptides during translation.c. During translation, DNA codes for mRNA, which codes forpolypeptides during transcription.d. none of the abovearrow_forward
- What is the difference between a structural gene and a regulator gene? a. Structural genes are transcribed into mRNA, but regulator genes aren’t. b. Structural genes have complex structures; regulator genes have simple structures. c. Structural genes encode proteins that function in the structure of the cell; regulator genes carry out metabolic reactions. d. Structural genes encode proteins; regulator genes control the transcription of structural genes.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. What would be the effect on the cell line that possesses the mutation, especially LNS protein levels?arrow_forwardAlso, describe what happens when a nonsense mutation is introduced into the gene encoding transposase within a transposon and why is it more likely that insertions or deletions will be more detrimental to a cell than point mutations?arrow_forward
