- Bacteria have an enormous ability to adapt to new conditions. Which two of the following are they main factors behind this phenomenon? New mutations occur continuously with very high frequency in the genome of bacteria Bacteria generally have small genomes Bacteria have a short generation time The rate of DNA synthesis is very high in bacteria Presence of a selection pressure.Genetic engineering is a process causes the production of GMOs ( Genetically Modified Organisms) due to the ideas of biologists. The presence of the products contributes the division of the society in relation to GMOs effects. TASK: You serve as a genetic engineer, if you are given a chance what GMO would you like to produce? What to do: Give a name of your GMO Illustrate and/or describe your GMO List all the possible pros and consWhich of the following would be a good argument for opponents of genetically engineered food? A Gene manipulation makes animals we eat for food taste funny B Gene manipulation costs too much C Gene manipulation makes animals too big to care for D Gene manipulation could cause an animal disease to cross over to humans
- Which of the following statements about genetically modified organisms (GMOS) are correct? Select all that apply. Question 19 options: Transgenic bacteria are used to produce protein for human consumption. Transgenic mice are frequently used to study the effects of gene mutations. Transgenic bacteria are used to produce human growth hormone. Transgenic goats have been engineered with a human gene that produces blood anticoagulant protein.What is agri-biotechnology and GMOs (Genetically Modified Organism)? Why does this remain to be one of the controversial issues in science today? Include in your discussion the communication challenges for both agri-biotechnology and GMOs as well as your own inputs/strategies in bringing this science to the public. Cite your sources.The spread of antibiotic resistance genes is an example of evolution. Explain how this is evolution using the framework of natural selection. Make sure you include what genes are evolving and what is the selective agent or selective pressure.
- Which of the following best describes the relationship between drug-resistant bacteria and antibiotic use? O When exposed to antibiotics, the drug resistant bacteria will die first, leaving behind the beneficial bacteria O tis acceptable to discontinue a course of antibiotics as soon as you feel better. This keeps fewer of the good bacteria from being killed O Antibiotic use prompts the bacteria to develop a drug resistant gene O The drug-resistant variant of bacteria is already in the bacterial population. Antibiotics provide the selective pressure favoring these bacteriaDo you agree or disagree why? Prior to this video I had not been introduced to the concept of genetically modified babies or "designer babies". However, a concept that was brought up in comparison to the designer babies was IVF babies. This concept is more familiar to me and made me think of the great possibilities designer babies could bring, but at what cost? As IVF first became popular it seemed to be well known that was was a possibility for well-off financially families. Although designer babies may have benefits such as lowering the risk to develop hereditary diseases, I don't think this concept would be widely accessible to varying income levels.Scenario C: Your Uncle raises beef cattle and is considering adding low amounts of antibiotics to their feed because he heard it makes them grow larger. Explain to him: The concept of using antibiotics for "essential use only." The process of natural selection. How low levels of antibiotics select for resistant bacteria. How these antibiotic resistant bacteria can then be harmful to not only cows, but also humans.
- The 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?Antibiotics such as tetracycline, streptomycin, and bacitracin are small organic molecules that are synthesized by particular species of bacteria. Microbiologists have hypothesized that the reason why certain bacteria make antibiotics is to kill other species that occupy the same environment. Bacteria that produce an antibiotic may be able to kill competing species. Eliminating competitors provides more resources for the antibiotic-producing bacteria. In addition, bacteria that have the genes necessary for antibiotic biosynthesis contain genes that confer resistance to the same antibiotic. For example, tetracycline is made by the soil bacterium Streptomyces aureofaciens. Besides the genes that are needed to make tetracycline, S. aureofaciens also has genes that confer tetracycline resistance; otherwise, it would kill itself when it makes tetracycline. In recent years, however, many other species of bacteria that do not synthesize tetracycline have acquired the genes that confer…Malaria is an infectious disease caused by parasites transferred to humans via mosquitos. Researchers have been working on creating a transgenic mosquito that is resistant to the malaria parasite. Researchers hope that this malaria-transgenic mosquito could eventually be released into nature. Identify one risk and one benefit of this type of approach
