Used to help identify infectious agents genome - correct answersall of an organism's genetic material What is a BLAST? - correct answersa database of the DNA of known organism; Basic local alignment search tool. How is PCR different when scientist are trying to sequence DNA vs using it to identify the owner of the DNA? - correct answersThey only tag it with fluorescent markers when they are sequencing Each colored peak on graph - correct answersa different nucleotide What do scientists use in order to make sure that the pathogen's DNA is being sampled and to ensure that we are not getting the human DNA in our results as well? - correct answersprimers Sometimes things go wrong in the lab when trying to properly sequence the DNA. If the necessary fluorescent markers were not added properly (or stopped functioning properly) which of the following would be a direct result? - correct answersThe sequence of nucleotides could not be determined as the genetic material passed through the laser DNA SEQUENCING, (next Blast) - correct answershow scientist determined the precise order of nucleotides within a DNA molecule First step in Sequencing: - correct answersisolate DNA of pathogen with PCR using Primers. Second step of DNA Sequencing: - correct answersDNA polymerase (adds on nucleotides) taq Three step of DNA sequencing: - correct answersFree floating Nucleotides used for PCR fourth Step of DNA sequencing - correct answersFluorescently tagged nucleotides cause different length of fragments. automatic sequencer - correct answerstube is filled with a buffer solution. Fluorescently tagged fragments go in the tube. Shortest fragments pass by the laser which then data pops on the screen. Antibodies - correct answersProduced by B lymphocytes and destroy antigens Antigens - correct answersForeign material that invades the body ElIZA - correct answersEnzyme-linked immunosorbent assay is a test that combines enzymes and antibodies to test for a presence of diseased antigen. They can detect disease agents in body fluids. Qualitative - correct answersPostive or negative Quantitative - correct answersdetermine how much of the detected substance is present.

You then perform a serial dilution with a dilution factor of 1/2. What is the concentration of well 5? DON'T write the unit...just the number! - correct answers5 During ELISA, the solution turned blue when which two things came into contact? Please select BOTH things in order to receive credit. - correct answerssubstrate and enzyme __________ have surface _________ where _________ attach - correct answerspathogens, antigens, antibodies A doctor orders an ELISA test for two patients. The results show that both had a color change from clear to blue. Patient A has results that are dark blue while the results for Patient B are light blue. What is most likely the diagnosis? - correct answersPatient A is more infected than
