Chapter 20, Problem 17TYK
Summary Introduction
Introduction: Recombinant DNA (rDNA) technology involves the modification of an organism’s gene by inserting a gene of interest into it, so that the organism produces large amounts of required protein product. This involves many enzymes like restriction enzymes to splice the

Students have asked these similar questions
Write the advantages and disadvantages of applying such application in the DNA of an organism.
a. Drug delivery systems that are based on bacterial or viral host.
b. Producing genetically modified organisms to enhance food production.
c. Combining two or more genes in one organism to enhance its traits.
d. DNA manipulation of certain species to produce organs for harvesting.
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?
2) Transgenic animal refers to an organism whose genome has been altered by the transfer of
a gene or genes from another species or breed. Cows, pigs and goats had been modified
especially for pharmaceutical purposes. Explain three (3) most used transfection technology
for the creation of transgenic animals.

- AquAdvantage salmon is a genetically modified (GM) Atlantic salmon developed by AquaBounty Technologies. The Food and Drug Administration (FDA) has approved the company's application to allow the entry of this GM salmon into the United States food supply late last year. The FDA announced that: "AquAdvantage salmon is as safe to eat as any non- genetically engineered (GE) Atlantic salmon, and also as nutritious." However, opponents of genetically modified food are claiming that the AquAdvantage salmons could pose a serious environmental risk to the marine ecosystem if the engineered fishes escape from the farms. These transgenic salmons would be a big threat to the wild salmons. Justify this statement.arrow_forwardThe use of genetically modified organisms in areas of agriculture and medicine is favored by many. However, knowing that possible risks may occur as a result of their usage, organizations who are pro-people’s right deem it necessary to oppose the commercialization of these genetically engineered products. As a youth, what is your stand to this issue and how would you make your position clear?arrow_forwardSelect the correct statement/s regarding the application of biotechnology in the field of health and medicine. The clones with mutated genes develop on the photographic film due to the complementarity of the probe with the mutated gene in auto- radiography. Preservatives, stabilizers, and adjuvants are added to recombinant DNA vaccines in order to allow the usage of multi-dosage vials, enhancement in storage life, and immune response.
