Which of the following can be used to carry foreign DNA into host cells? Choose all correct answers. a. RNA b. viruses c. PCR d. plasmids e. lipid clusters f. blasts of pellets g. xenotransplantation h. nanoparticles
Figure 17.7 You are working in a molecular biology lab and, unbeknownst to you, your lab partner left the foreign genomic DNA that you are planning to clone on the lab bench overnight instead of storing it in the freezer. As a result, it was degraded by nucleases, but still used in the experiment. The plasmid, on the other hand, is fine. What results would you expect from your molecular cloning experiment? There will be no colonies on the bacterial plate. There will be blue colonies only. There will be blue and white colonies. The will be white colonies only.
Linkage analysis. is used to create a physical map is based on the natural recombination process requires radiation hybrid mapping involves breaking and rejoining of DNA artificially
Match each term with the most suitable description. ____ DNA profile a. GMO with a foreign gene ____ Ti plasmid b. alleles commonly have them ____ eugenics c. a persons unique collection of short tandem repeats ____ SNPs d. selecting desirable traits ____ transgenic e. genetically modified ____ GMO f. used in plant gene transfers
Genetically Modified Foods The creation of transgenic crop plants using recombinant DNA methods involves the transfer of just one gene or a small number of genes to the plants, in contrast to classical breeding methods in which hundreds or even thousands of genes are transferred at once. Explain why this is true. If fewer genes are transferred during the creation of transgenic crops, why are some people afraid that they are dangerous?
GMOs are created by. generating genomic DNA fragments with restriction endonucleases introducing recombinant DNA into an organism by any means overexpressing proteins in E. coli all of the above
What Art the Features of the Series of -omes? Define the following terms: a. Genome b. Transcriptome c. Proteome d. Metabolome e. Fluxome
Recently, scientists discovered that a rare disorder called polkadotism is caused by a bacterial strain, polkadotiae. Mice injected with this strain (P) develop polka dots on their skin. Heat-killed P bacteria and live D bacteria, a nonvirulent strain, do not produce polka dots when injected separately into mice. However, when a mixture of heat-killed P cells and live D cells were injected together, the mice developed polka dots. What process explains this result? Describe what is happening in the mouse to cause this outcome.
