Ashworth College BIOLOGY, S SC160 Biology exam 5. 5 / 5 points Genetically modifying human eggs and sperms may directly affect future generations. Question options: TranSTR analysis is a DNA pr... ofiling technique that makes use of the fact that different people have different numbers of repeats of short DNA sequences at certain sites in the genomeslation converts the information stored in __DNA______ to ___RNA_____. Question options: What is the definition of a genetically modified organism? Question options: A) an organism carrying a gene that was acquired by artificial means B) an organism in which a particular mutation has appeared for the first time C) a cloned organism carrying two different alleles View Feedback 5 / 5 points To make restriction fragments, a DNA sample is treated with restriction enzymes. Question options: A DNA fragment with the sticky end sequence TGGCA will bind with another DNA fragment with the sticky end sequence ________. Question options: A) TGCCA B) ACCGT C) TGGCA D) ACGGT View Feedback 5 / 5 points Which is the last step in the production of a recombinant DNA plasmid? Question options: A) cloning B) using DNA ligase to join DNA fragments C) cutting the gene of interest into fragments D) allowing the reproduction of the bacterium bearing the recombinant plasmid View Feedback 5 / 5 points What can act as a vector to introduce new genes into a cell? Question options: A) primers B) ligase C) restriction enzymes D) plasmids View Feedback 5 / 5 points The definition of a genetically modified organism is an organism carrying a gene that was acquired by artificial means. Question options: What is the definition of a "transgenic organism?" Question options: A) an organism that is the first of its kind to show a particular phenotype B) an organism in which a genetic defect has been corrected using gene therapy C) an organism containing a gene from another species View Feedback 5 / 5 points DNA Polymerase is the enzyme used to bind DNA fragments together. Question options: You are attempting to link an individual to a crime. The only evidence you have is a tiny drop of blood. How can you use this drop of blood to definitively make the association? Question options: A) You can use the sample to determine the individual's blood type. B) You can use gel electrophoresis to determine the length of the DNA found in the sample. C) You can use PCR to increase the amount of DNA available for STR analysis. View Feedback 5 / 5 points Restriction enzymes are obtained from ________. Question options: A) archaea B) eukaryotes C) viruses D) bacteria View Feedback 5 / 5 points Gel electrophoresis separates DNA fragments on the basis of differences in their A:C ratio. Question options: The process of making multiple copies of a gene by inserting it into a host genome and culturing the host is an example of ________. Question options: A) gene cloning B) PCR C) STR analysis D) whole-genome shotgun method View Feedback 5 / 5 points What evidence led to the confirmation that Albert DeSalvo was the Boston Strangler? Question options: A) an analysis of blood types from the crime scene B) an analysis of fingerprints from the crime scene C) an analysis of DNA from the crime scene D) an analysis of witness testimony from the crime scene View Feedback 5 / 5 points What is the definition of a genetically modified organism? Question options: A) an organism carrying a gene that was acquired by artificial means B) an organism in which a particular mutation has appeared for the first time C) a cloned organism carrying two different alleles View Feedback 5 / 5 points What is the best definition for recombinant DNA? Question options: A) a type of nucleic acid that includes both RNA and DNA strands B) DNA that includes nucleotides from two different sources C) an alternate form of DNA that is the product of a mutation View Feedback 5 / 5 points The goal of the Human Genome Project was to determine the nucleotide sequence of all of the DNA in the human genome Question options: Restriction enzymes are obtained from eukaryotes. Question options: A vaccine works by stimulating the immune system to develop lasting defenses Question options: True False 100 / 100 - 100 % 100 / 100 - 100 % Done [Show More]
