- In a gene mapping experiment, DNA from a prototrophic E. coli strain is transformed into an E. coli strain mutant (auxotrophic) for the genes gal, pro, and lac. Some resulting transformants were found to be auxotrophic only for pro, and some only for gal, but no lac- only auxotrophs were observed. Based upon these results, which gene is in the middle? a. gal b. lac c. pro d. cannot be determined c. the genes are not on the same chromosomearrow_forwardAs evolution is the change in allele frequency in a population over time … Explain the evolution of bacteria in terms of changes to the frequency of the NDM-1 gene.arrow_forwardExplain the difference between gene modification and gene addition.Are the following examples of gene modification or gene addition?A.

- A research project was conducted to study the effect of permethrin when used as insecticide, but some mosquitoes have become resistant to permethrin. The research included the following steps. A sample of mosquitoes was treated with the insecticide. The majority of the mosquito population died, but a small percentage survived. From the survivors, a line of resistant mosquitoes was bred. The DNA of the non–resistant strain was compared with DNA from the resistant strain. Before analyzing the DNA, the researchers conducted an experiment to make sure they had produced a strain of resistant mosquitoes. This experiment included the following steps. A sample of wild–caught mosquitoes and a sample of the resistant strain of mosquitoes were treated with permethrin. The percentage of mosquitoes surviving in each sample was calculated. The responding variable in this experiment was the Select one: a. exposure of mosquitoes to permethrin b. resistant mosquito sample c. number of mosquitoes…arrow_forwardWhich of the following is an example of horizontal gene transfer? a. the transmission of an eye color gene from father to daughter b. the transmission of a mutant gene causing cystic fibrosis from father to daughter c. the transmission of a gene conferring pathogenicity (the ability to cause disease) from one bacterial species to another d. the transmission of a gene conferring antibiotic resistance from a mother cell to its two daughter cells e. all of the abovearrow_forwardWhich of the following evolutionary changes is an illustration of horizontal gene transfer? the human point mutation which changes a T into an A in the sickle-cell b-globin gene B. origin of the tetraploid potato (Solanum tuberosum) from its diploid ancestor (Solanum stenotomum) non-disjunction of the duplicated human chromosome 21, causing Down’s syndrome D. the green sea slug acquiring the genes for making chlorophyll from the chloroplasts of green algae the single gene deletion which can reduce the variety of mating types in yeastarrow_forward
