- Describe the mechanistic steps through which gene therapy might be used to cure a disease that is caused by mutations in "Gene D". A potential patient is reluctant to undergo this treatment, because they remember hearing about adverse incidents from gene therapy studies conducted decades ago. What relevant details might you tell them, in order to inform them on this topic?.What are mutation breeding?Although it is well known that X-rays cause mutations, they are routinely used to diagnose medical problems, including potential tumors, broken bones, and dental cavities. Why is this done? What precautions need to be taken?
- There are a range of ethical issues associated with cloning. However, many of these are not applied to cloning plants. Explain why the idea of cloning an entire plant is generally accepted while cloning an entire human is not.All of the following are true about the design of the Beadle and Tatum experiment (one gene one polypeptide) EXCEPT: A. Used X-rays to generate auxotrophs B. Depended on the use of the bacteria, N. crassa C. Examined the way in which amino acid biosynthesis occurs D. Added nutrient intermediates to rescue lethal mutations included the study of conditional mutants E. Led to the one-gene-one polypeptide hypothesis.To produce transgenic plants, plant tissue is exposed to Agrobacteriumtumefaciens and then grown in media containing kanamycin, carbenicillin, and plant growth hormones. Explain the purpose behind each of these three agents. What would happen if you left out the kanamycin?
- It has been suggested that it would make the study of human diseases easier if cloned transgenic animals were produced that carried faulty versions of human genes (e.g., the gene that causes cystic fibrosis). a. Why would such animals be useful in medical research? : b. What ethical questions are raised by the creation of such transgenic animals?A paper hypothesizes that white flowers are unable to produce anthocyanins (purple pigments) because they lack a functional “A” protein. However, it is also possible that an unknown gene is responsible for the lack of anthocyanins. Now that they have isolated DNA sequences of the “A” allele, design an experiment to use these DNA sequences to distinguish between these two hypotheses.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.
