True False on 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. on 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 on 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 on STR analysis is a DNA profiling technique that makes use of the fact that different people have different numbers of repeats of short DNA sequences at certain sites in the genome. Question options: True

False on A vaccine works by stimulating the immune system to develop lasting defenses Question options: True False on 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 Done
