Scientists are concerned that bacteria will be resistant to all antibiotics within the next decade. Using your knowledge of genetics, briefly describe one method by which bacterial populations can develop drug resistance. Do NOT use "mutation" as your answer. Be more specific. From what you learned in this chapter, how would the bacteria be able to change or mutate in order to become antibiotic resistant? Explain why the following statement is false: Sexual reproduction is the only mechanism for genetic change. Do NOT use Mutation as your answer. Be more specific: what are other mechanisms by which microbes can change or mutate their DNA?

Is gene transfer a form of eugenics? Is it advantageous to use gene transfer to eliminate some genetic disorders? Can this and other technology be used to influence the evolution of our species? Should there be guidelines for the use of genetic technology to control its application to human evolution? Who should create and enforce these guidelines?
Humans have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization that significantly modify genomes of organisms. Why do you think modern genetic engineering, which often entails introducing or modifying only one or a few genes, has met with so much opposition? Should some forms of genetic engineering be of greater concern than others? Explain.
Which of the following statements correctly describes a process by which bacteria become resistant to antibiotics? A. bacteria reproduce slowly, allowing mutation to become widespread in a population. B. some bacteria produce exotoxins that breakdown antibiotics, rendering them nonfunctional C. conjugation spreads antibiotic resistance genes rapidly in a population D. antibiotics cause mutation in bacteria, making them resistant.
The graphs show a spectrum of antibiotic-resistant organisms, from 1 to 11, where 1 is the least-resistant and 11 is the most resistant. Notice that before the population replicates (graph on the left), there are no bacteria with resistance 2 or 3, OR 11. But after the population replicates, there are some bacteria with these resistance levels, indicated by the yellow arrows. Which of the following explains the origin of the bacteria pointed at by the yellow arrows? A mutations that happen when the cells in the population replicate their DNA and divide in two B some bacteria just shift one way or the other. C bacteria learn how to become more resistant
Briefly discuss the following questions in 3 to 5 sentences. What is horizontal gene transfer? What are the three mechanisms for this to occur in bacteria? What are the components needed for the processes of transformation, conjugation, and transduction? How does each process occur? What genes are involved in each process? How do generalized and specialized transduction differ? What is the end result of each? What is recombination? What is the importance to bacteria & archaea? What are the two types of recombination? What are the details of each type? What components are needed for each type?
Which among the following statements is not true about mutations? * a.) It may either occur at the chromosomes or at the sequence of nucleic acids. b.) It is caused either by mutagens or through hereditary genes. c.) All mutations cause diseases and disorders in the developing organism. d.) All mutations causes a change in the structure or sequence of the genetic material.
Do you see any potential problems with inserting pieces of a retroviral genome into humans? If so, are there ways to combat or prevent these problems? Explain your answer.
What is an example of advancements in genetic engineering or gene modification that have occurred over the last 20 years and what is the impact of this upon our everyday lives?
why do the bacteria grow up to the edge of the area with antibiotics, pause, then continue to grow across the area with antibiotics? A) The antibiotics caused mutations in the DNA of the bacteria, making them resistant to the antibiotics. B) The bacteria mutated as a survival response to the presence of antibiotics, enabling the bacteria to become resistant to the antibiotics. C)A few bacteria experienced random mutations in their DNA, which allowed some of them to grow even though antibiotics were present. D) Researchers added antibiotic resistant bacteria to the culture, so that the bacteria would continue to grow across the area with antibiotics.
If you had the ability to do gene editing with ONE gene for the betterment of human kind, which one would you choose, and why? Assume you could either change an abnormal allele associated with a disease, such as the cystin gene associated with Cystic Fibrosis to its normal wild type, or add a pre-existing human allele to a genome.
Now that cloning is possible, should it be used to clone animals that are near extinction? What are the possible ramifications of this when it comes to genetic diversity and size of the gene pool?
You are discussing with some of your bio major friends who have not taken Genetics and your non-bio major friends about how characteristics such as blue eye, light skin pigmentation, and light hair color, derived from a mutation that occurred about 10,000 years ago in Europe. Your friends are not very happy that you used the word mutation to describe the origin of human characteristics associated with light pigmentation. At that moment you only recall that green eye, fair skin and red hair in Neanderthals was due to other alleles and you mention that to them as an example of genetic determinants in species of the genus Homo. They are not convinced of your choice of the word mutation. Then you remember part of one of the papers that you read for Minicourse 5 regarding the OCA2 allele. “OCA2, homologous to the mouse pink-eyed dilution gene, encodes the human protein P, an integral membrane protein involved in both the transport of tyrosine and that helps in the regulation of…
