Introduction:
The recombinant DNA technology involves isolation of genetic materials (DNA) from donor organisms (human, plant, or microorganism) and inserts them into recipient organisms after genetic manipulation. The main tools involved in the techniques are

- A scientist wants to study the cytochrome c gene of a fruit fly. The DNA for the gene is extracted and subjected to several treatments. If a disease were identified as being caused by defects in the cytochrome c gene, then the copy isolated could be used for what? A. PCR B. gene therapy C. stem cell work D. DNA fingerprintingarrow_forwardMatch the process to the step in producing a transgenic plant using the Ti plsmid method. 45. A gene is isolated and the process starts. 46. The recombinant DNA has this so it can be found later. 47. The plasmid enters here. 48. A. tumefaciens infects target organism. 49. The selectable marker allows transgenic plants to survive antibiotic. 50. Transgenic plant cells are isolated. 51. Transgenic plants are prepared for life in the soil. Kanamycin is added to culture. b. The isolated transgenic cells are grown into multicellular organisms. C. Ti plasmid picks up gene of interest. d. Bacterium Agrobacterium tumefaciens takes this up. A selectable marker makes the cell resistant to kanamycin. a. e. f. Antibiotics kill any remaining bacteria. g. The host plant is selected and exposed to the new DNA.arrow_forwardWhat is the role of CTAB in DNA isolation? A. Neutralize negative charge of DNA B Precipitate DNA C Remove polyphenols and tannins D Precipitate polysaccharidesarrow_forward
