Scientists created a new variety of bacteria by inserting the gene for human insulin production into their genome. The insulin produced by this modified bacteria regulates blood sugar in people with type 1 diabetes. The insulin produced by the bacteria causes no allergic reactions compared to the insulin extracted from mammals. What does this process demonstrate?

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 bacteria
Researchers produced transgenic corn that contained an extra codon for phenylalanine andhad a high oil content. Suppose an existing commercial variety of corn was modified in thesame way and sold to farmers. Would you consider this variety to be a genetically modifiedorganism ? Should the corn produced by this variety be labeled as agenetically modified food product?
Antibiotics such as tetracycline, streptomycin, and bacitracin aresmall organic molecules that are synthesized by particular speciesof bacteria. Microbiologists have hypothesized that the reason whycertain bacteria make antibiotics is to kill other species that occupythe same environment. Bacteria that produce an antibiotic may beable to kill competing species. This provides more resources forthe antibiotic-producing bacteria. In addition, bacteria that havethe genes necessary for antibiotic biosynthesis contain genes thatconfer resistance to the same antibiotic. For example, tetracyclineis made by the soil bacterium Streptomyces aureofaciens. Besidesthe genes that are needed to make tetracycline, S. aureofaciensalso has genes that confer tetracycline resistance; otherwise, itwould kill itself when it makes tetracycline. In recent years, however,many other species of bacteria that do not synthesize tetracyclinehave acquired the genes that confer tetracycline resistance.For example,…

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.
For instance, what would happen if ice-minus bacterial genes were transferred to strains of bacteria that are accustomed to living under cold conditions? ( Should genetically engineered microbes be released even in “controlled” experiments that might result in beneficial applications of biotechnology? How do you think the scientific field can prevent the escape of genetically altered microbes in field experiments?
You are helping a patient who you think has CJD. They want you to explain how this happened. Which explanation below is NOT correct? O spontaneous misfolding of the normal prion with age O possible transfer of abnormal prions on contaminated surgical instruments O overuse of antibiotics O possible transfer of abnormal prions from blood transfusion O possible transfer of prions through organ transplant O consumption of beef from cattle with BSE Question 65 Below are stens in the evolution/emergenco of vCD
The discovery and mass-production of antibiotics has triggered a revolution in medicine, decreasing hospitalization times, shortening the course of diseases, and ultimately increasing peoples' lifespans. However, soon after the first major antibiotic, penicillin, was put into widespread use around 1940, people soon found that some bacteria were tougher to kill, which were the first signs of antibiotic resistance in bacteria. Over the years bacteria have been able to develop resistance against many different types of antibiotics, and some bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) is resistant to almost every antibiotic in use today. Antibiotic resistance has become so severe that in 2014 the World Health Organization published a report that speculated of a "post-antibiotic era" where antibiotics were no longer a main method of disease treatment. In this week's forum, please read summary of the World Health Organization's report (linked here and in the…
Humans perfected the use of recombinant DNA technology to produce human insulin from bacteria. Outline steps in this process of using E. coli as to host cells.
In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was beriberi.Symptoms of the disease include weakness and loss of appetite, victims often died of heart failure.Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria fromthe blood of patients with beriberi. The injected chickens became sick. However, so did a group ofchickens that were not injected with bacteria.One of the scientists, Dr. Eijkman, designed a new experiment based on his ownobservations. Before the experiment, all the chickens had eaten whole-grain rice, butduring the experiment, the chickens were fed polished rice. Dr. Eijkman researchedthis interesting case and found that polished rice lacked thiamine, a vitamin necessaryfor good health.1. State the question or problem that Dr. Eijkman investigated. 2. What was the original hypothesis? 3. What was the manipulated (independent) variable and the responding (dependent) variable? 4. Write a…
Antibiotic-resistant bacteria have become a stubborn challenge for scientists. Should bacteriophages be used to save the lives of patients in which other treatments have failed?
It’s late summer and a new influenza virus strain has appeared in chickens across the country.It’s an H1N1 strain of Influenza A, like the Spanish flu that caused one of the deadliest pandemics in humanhistory, back in 1918. In that case too it started as an avian flu that mutated and jumped directly from birdsto humans.You are a researcher at the NIH and the President gives you 24 hours to predict the chances that this couldturn into the next “Spanish flu”. They also ask you to present a plan for a vaccine that will specifically targetthis new strain.The full sequence of the Spanish flu virus is available and is also known which mutations where key toconfer it both high infectivity and high virulence. Also the frequency of mutations of this family of viruses isknown.Samples of the new strain currently infecting chickens are also available to you.You are at the NIH laboratories in Bethesda, MD, and you have infinite resources (equipment and staff) atyour disposal.Remember: Influenza…
