If a scientist wanted to introduce a transgene into a plant, which of these techniques would they be likely to use?
A.) Inject a P element vector into a pollen grain.
B.) Inject a genetically modified nucleus into an enucleated plant cell.
C.) Inject a transgene into a seed.
D.) Infect plant cells with bacteria containing T-DNA.
this is an example of biotechnology: In order to increase the yield of oil from canola, research focused on ways to reduce competition from competitor weed plants. Weeds can be controlled by spraying with a herbicide that interferes with biological processes, like amino acid anabolic reactions, in the plant cells. A mutant of canola that is resistant to herbicides is sometimes grown in fields that are sprayed with the herbicide. The majority of canola in Canada, though, is genetically modified to be resistant to herbicides. also use the link: https://youtu.be/VS3kcwgIwm0
Question:
Evaluating Biotechnologies in Food Systems
As we practice being able to describe choices in Biology you will use this consolidation task to organize details about the advantages and disadvantages of biotechnologies. In an ideal world, all solutions to improving our food system would have no negative consequences. But issues in Biology involve the interaction of many different factors and changes in one…
Bt eggplant is a genetically-modified eggplant developed by Filipino scientists. It was developed to become pest-resistance containing the gene of the bacterium Bacillus thuringiensis which contains toxins that are lethal to some insects including the pest bollworm. Currently, it is under controversy because of a legal battle between its supporters and those who are against it.
Should the government ban the production, commercialization and consumption of the said Product?

- Genetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?arrow_forwardBacteria are often the preferred hosts for genetic engineering projects by splicing in novel genes from eukaryotes into plasmids, which are moved into competent bacteria. For instance, the gene for human insulin was isolated and moved into a bacterium, which can now produce the much-needed chemical. Previously, type 1 diabetics had to rely on professionals that gathered insulin from human cadavers, cows, and pigs. In order for this feat of genetic engineering to occur, researchers had to start with an unspliced mRNA transcript for h insulin. Agree/Disagree? Explain your response.arrow_forwardPlease help!

Which gene(s) are likely mutant or missing inyour special strain? You have a second strain ofNeurospora that makes neither citrulline nor argininebut does make ornithine. Which gene(s) are mutant ormissing in this strain?arrow_forwardOkay, maybe GMOs have decent uses but it can't all be good. I've heard all of the following about GMOs. Which ones are realistic concerns? select all that applys a)Some GMO are patented and farmers must buy seeds every year rather than saving them from their crops. b)GMO's cause allergies at a greater rate than crops produced by cross-breeding. c)Inserted genes produce amino acids not found in nature. d)Inserted genes may escape into wild plants near farmed fields.arrow_forwardIn their Nobel Prize-winning experiments, Beadle and Tatum exposed fungal spores to X-rays to induce mutations. If the mutants had mutations in the arginine metabolic pathway, they would grow in ------minimal medium (wrong answer), but NOT in -------complete medium (wrong answer).arrow_forward
- You are studying a biochemical pathway and isolate Neurospora mutants I, II, and III.Mutant I can grow if you supplement the medium with Z.Mutant II can grow if you supplement the medium with X, Y, or Z.Mutant III can grow if you supplement the medium with X and Z, but not with Y. Draw a biochemical pathway that shows the correct order for compounds X, Y, and Z and for the enzymes that each mutant is defective for.arrow_forwardSuppose that you are hired by a biotechnology firm to produce a strain of giant fruit flies, by using recombinant DNA technology, so that genetics students will not be forced to strain their eyes when looking at tiny flies. You go to the library and learn that growth in fruit flies is normally inhibited by a hormone called shorty substance P (SSP). You decide that you can produce giant fruit flies if you can somehow turn off the production of SSP. SSP is synthesized from a compound called XSP in a single-step reaction catalyzed by the enzyme runtase: XSP———————>SSP runtase A researcher has already isolated cDNA for runtase and has sequenced it, but the location of the runtase gene in the Drosophila genome is unknown. In attempting to devise a strategy for turning off the production of SSP and producing giant flies by using standard recombinant DNA techniques, you discover that deleting, inactivating, or otherwise mutating this DNA sequence in Drosophila turns out to be extremely…arrow_forwardIn bacteria, Which of the following mechanisms is the least probable in promoting antibiotic resistance?

- Genetically modifying seeds to produce herbicide-resistant plants that increase crop yields has revolutionized modern agriculture. However, genetically modified organisms (GMOs) have come under fire in recent years, with consumer groups calling for mandatory GMO labeling on all food packages that contain GMO ingredients. GMO labeling laws have been in force in the European Union and other countries for several years, but the threat to the U.S. food industry is only now surfacing. Although bills requiring GMO labeling have been introduced in many state legislatures, Vermont is the only state where such a law has so far withstood the first round of legal battles from the industry. Leading chemical companies, including Monsanto, BASF, and DuPont, are the world’s largest suppliers of seeds that grow the food that feeds the world. To counter the GMO labeling threat, they now are turning to mutagenesis as an alternative technique to create herbicide-resistant crops. Mutagenesis mimics the…arrow_forwardCorn 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?arrow_forwardOne of the reasons why phage therapy has not been applied widely is that bacteria can become resistant to bacteriophages as well, through mutations in genes encoding for specific proteins. What would be a protein in the bacterial cell that, if mutated, would make that cell resistant to phage infection?arrow_forward
