Which of the following is false regarding corn plants that were genetically modified to produce the Cry protein? Group of answer choices You would need to add a corn enhancer to the Ti plasmid Reverse transcription of the Cry mRNA is not needed, as corn plants are eukaryotes The gene necessary for Cry protein synthesis is present in all cells of the corn plant, however, it is not expressed in the endosperm You would need to remove tumor inducing genes from the Ti plasmid You would need to add a eukaryotic promoter, active in corn, to the Ti plasmid
Genetic engineering of plants provides an opportunity to alter their properties or performance in order to improve upon their utility. Such technology may be used to modify the expression of genes already present in the plants, or to introduce new genes of other species with which the plant cannot be bred conventionally. In fact, humans have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization that significantly modify genomes of organisms. How has this technology created novel genetic information by specific alteration of cloned genes? (provide an example). Why do you think modern genetic engineering, has met with so much opposition? Should some forms of genetic engineering be of greater concern than others? Explain. In your response provide a specific example from literature to describe the implications of this technology (good or bad).
Excluding leaf senescence, describe three instances of programmed cell death as a part of normal plant development.

These questions regard development in seeds. What part of the rice plant is used to make rice crispies and what part of the wheat plant (which is the seed) is used to make wheat germ?
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…
