- Which statement about transposons is INCORRECT? a.A transposon is a small fragment of DNA that can move from one location in a chromosome to another location in the same chromosome. b.Transposon insertion into a gene causes a mutation that can be reversed by removal of the transposon. c.Transposon movement often occurs when the cell is under genomic stress. d.In nature, insertion of a transposon can be deliberately added into a harmful gene to enhance survival.arrow_forwardFor eukaryote cells to evolve into new types of eukaryotic organism, which of the following would one expect to occur? a) All the cells are identical b) The endoplasmic reticulum is not involved. c) These specialized cells activate only the genes in their nucleoid area. d) Cells must be getting new genetic mutations and more DNA e) none of these are true.arrow_forwardWRITE ABOUT A THEME: INFORMATION In a short essay(100–150 words), discuss how the genetic basis of life plays acentral role in biotechnologyarrow_forward

- Hox genes are activated in specific regions of the body (e.g. back of the head) and activate other genes to build specific structures in those regions. This was largely discovered by looking at the effects of mutants of the various hox genes. What other technique would provide information on the action of hox genes? Group of answer choices A. copy hox genes and place them in bacteria B. copy hox genes and place them in plants C. completely remove all hox genes from the genome D. change the control of hox genes so that they are expressed in different body regions E. reverse the order of the hox genes on the chromosomearrow_forwardWhich of the following statements is/are true about gene regulation in bacteria? Choose all that could apply Multiple answer apply A genes with related functions are often grouped together and are transcribed into a single piece of RNA B small molecules act as sensors and bind DNA to change its 3D shape C enhancers are commonly used to regulate transcription D repressor proteins block transcription by binding to operator sequences E activator proteins bind near promoters and increase the efficiency of transcriptionarrow_forwardThe CFTR gene is very well conserved from mice to humans. What conclusions can you make about CFTR based on this information? A. The coding sequence of the CFTR gene is less susceptible to mutation B. CFTR is just as susceptible to mutation as other genes, but many CFTR mutations are lethal thereby preventing them from being passed on C. The protein encoded by the CFTR gene has a critical function in those organisms D. A and C only E. B and C onlyarrow_forward
- What is the advantage of studying the mRNA present in a cell rather than the DNA? A. The mRNA is more chemically stable at room temperature. B. The mRNA identifies which genes are expressed. C. The mRNA identifies inheritance patterns. D. The mRNA is better able to undergo PCR.arrow_forwardComparing DNA sequences in different species indicates that more DNA segments that do not code for protein have been conserved (unchanged) than protein- coding regions. These non-protein-coding regions areinterpreted as gene regulatory elements. Suggest why gene regulatory elements have not undergone many changes during the course of evolution.arrow_forwardhow would alterning patterns of gene expression in prokaryotes would most likely serve an organism's survival?
