To review:
The following:Â
1. The importance of considering the effects of developing insect resistance to an insecticidal plant before developing a transgenic crop.
2. The process of designing the transgenic plants to limit the possibility of insects developing resistance.
Introduction:
The ability of insects to resist the effect of an insecticide to which they were once sensitive is called insecticidal resistance. Resistance can be developed by many factors. Few individuals in the population of insects may carry the genes for resistance. Upon exposure to insecticides, the insects carrying the resistant genes are favored by nature and outbreed the insects that do not carry resistant genes.

- what are some of the benefits of producing transgenic crops for farmers and for consumers? List at least three benefits.arrow_forwardDiscuss the societal impacts of the use of transgenic Golden Rice.

- Describe a method of making transgenic plants.arrow_forwardDescribe in general terms the steps involved in creating transgenic plantsarrow_forwardWhat is homologous recombination and where/when does it typically take place in an organism. Homologous recombination is also used experimentally during gene targeting. If you wanted to remove the function of the mouse gene fibroblast growth factor 4 (FGF4) using gene targeting by homologous recombination, what are the different aspects of a targeting vector you would need to make?arrow_forward
- One concern about using genetically-modified organisms is that many of the methods used to create them introduce into the genome DNA from a different species (i.e. foreign DNA). Which of the following methods has the lowest potential of introducing foreign DNA into the genome?A. A gene knockout in mouse using homologous recombination in ES cellsB. Introduction of a P element vector into the Drosophila germ-lineC. Deletion mutations introduced by CRISPR/Cas9D. Microinjection of a transgene into a mouse pronucleusarrow_forwardWhat do you know about transgenic crops. Explain in detail with examples.arrow_forwardWhat is a fluorophore? If you wanted to fluorescently label a brain cell, describe one way you could genetically label a brain cell using a transgenic approach and give one way you could genetically label a brain cell using a gene targeting homologous recombination approach.arrow_forward
