Step by step
Solved in 2 steps
- Corn has been genetically engineered to produce the anti-insect poison of a bacterium Bacillus thuringiensis. What is one benefit of this? What are some of the risks?Briefly discuss the following concerns of Biotechnology;(i) Monoclonal antibodies technology versus gene technology for cancer treatment.(ii) Traditional plant breeding versus Gene technology: Which is the more efficient way for pesticide resistant crop production?(iii) Chemical technology versus Enzyme technology in industrial application.(iv) Are genetically modified organisms (GMOs) a threat to the environment?Name the bacterium which is used to produce insect-resistant plants by genetic engineering.
- A botanist wanted to see if a new strain of corn could germinate in soil that was too salty for regular corn. She conducted a study on the germination success of seeds from the new strain that were exposed to various levels of salty soil, from zero to normal (100mg/L) to high (200mg/L) to very high (400mg/L) to normally lethal (800mg/L). a.) Write a formal hypothesis for this study b.) Does her data support or reject the hypothesis? Explainexplain the reason for the possibility of getting the reverse of the results in this experiment. result: flask A with germinated seeds temperature increases and flask B with boiled seeds temperature remain unchangedA laboratory in Japan performed a similar experiment on earthworms from different localities of the Japanese archipelago, but instead of linking trypsin activity within worms to anatomical features, they were interested in geographical differences in the ability of the worms to breakdown environmental pollutants using the enzyme polyphenol oxidase. The protocol was similar to the one you used, except that enzyme activity was measured from 100 µl of worm extract. Data obtained are displayed below: Replicate Amount of product liberated over 10 minutes (pmol) Locality Concentration of total protein in worm extract (ug/ml) Hokkaido 1 101 4 87 3 3 107 4 4 88 3 89 Hon-shu 1 126 2 120 3 156 4 4 153 5 119 4 Кyu-shu 1 103 4 2 99 3 94 4 108 3 110 Okinawa 1 88 3 2 90 4 3 96 6. 4 100 112 3 From the data in the table, calculate the specific activity of polyphenol oxidase (in units of umol/min/mg protein) from each locality, presenting the data as mean + standard error (n=5). You only need to show 1…

Effective control involves applications of chemical insecticides, increasing the cost of production and environmental pollution. The current genetically modified Bt crops have allowed great benefits to farmers but show activity limited to lepidopteran pests. This work reports on procedures adopted for integration and expression of a cry transgene conferring resistance to boll weevil and fall armyworm by using moleFour Brazilian cotton cultivars were microinjected with a minimal linear cassette generating 1248 putative lines. Complete gene integration was found in only one line (TO-34) containing one copy of crylla detected by Southern blot.
