Benjamin is a doctor trying to determine the cause of a mysterious illness affecting several patients. Which of the following methods would most definitively identify the pathogen responsible?
Consensus of the symptoms of those that are affected.
Presence or absence of a rash.
Response to antibiotics.
DNA sequencing.
A sample of spinal fluid is taken from a college student suspected to have contracted spinal meningitis. Which diagnostic test did we use to confirm the diagnosis ?
Culturing the spinal fluid and testing for bacterial colony growth in a Petri dish.
An ELISA test
DNA cycle sequencing
Protein Chromatography
Aiden is running an ELISA test in the lab to check for a specific infection. After completing the procedure, he notices that there is no color change in the test wells. What is the most likely reason for this result?
The sample contains no antigen
The sample contains no antibodies
The person it came from has a the disease
The sample was contaminated and we should ignore those results
Which component in DNA cycle sequencing causes the replication process to stop?
Fluorescent nucleotides
DNA primers
Taq polymerase
Heating and cooling during PCR
The collection, classification, storage and analysis of biochemical and biological information using computers, especially as applied to molecular genetics and genomics is known as which of the following?
DNA sequencing
Bioinformatics
Immunological assay
ELISA
Which technique is commonly used to rapidly increase the quantity of a specific DNA segment for analysis?
Gel Electrophoresis
Southern Blotting
Polymerase Chain Reaction
Cycle Sequencing
1 ml of solute is added to 8 ml of solvent. The tube dilution is
1/10
1/9
1/8
none of these
Mason is working in a medical laboratory and is using an ELISA test to analyze patient samples. Which of the following can Mason never determine using the ELISA test?
Concentration of antigens
Presence of disease
Genetic sequence of a pathogen
Order of infection
After adding the secondary antibody and enzyme complex to the ELISA, what is added next (after washing?)
substrate
primary antibody
enzyme #2
antigen
A solution is diluted by a factor of 1/4 for each consecutive tube. The concentration in tube #1 is 64 ng/dL. What is the concentration in tube #3?
4 ng/dL
1 ng/dL
0.25 ng/dL
1024 ng/dL
none of these
Abigail is working in a lab to identify a specific pathogen in a DNA sample using cycle sequencing. She isolates the DNA and denatures it. What should Abigail add next in order to make sure she is replicating only the pathogen DNA of interest?
Add fluorescently-tagged nucleotides
Add primers specific to the pathogen of interest
Run through PCR
Give up...there's no point
Charlotte recently caught a cold, and her immune system started producing antibodies. What is the function of these antibodies within her immune system?
Antibodies kill off any antigen that enters the body.
Antibodies are only made when you are given a vaccination for specific antigens.
Antibodies bind to specific antigens to flag for destruction.
Antibodies are part of an external defense mechanism.
After accidentally cutting your hand while cooking, you visit the clinic. The healthcare provider examines your injury, uses imaging to check for any foreign objects, cleans the wound, applies stitches, covers it with a sterile bandage, and gives you a prescription for antibiotics. Which types of medical interventions did you receive?
surgical
pharmacology
diagnostics
all of the above
A doctor orders an ELISA test for two patients. The results show a color change to blue for both patients. Patient A’s result is dark blue, while Patient B’s result is a lighter blue. What is the most likely reason for this difference?
Patient A has been infected longer
Patient B has been infected longer
The patients have been infected for the same amount of time
Neither patient is infected
Isla is working in a laboratory and receives a sample containing an unknown pathogen. She has sequenced the nucleotides from the sample and now needs to identify the pathogen using a search tool. Which of the following tools should Isla use?
ELISA
BLAST
DNA Sequencing
PCR
How the ELISA used in class both a quantitative and a qualitative test?
ELISA yields a plus or minus sign for presence of antigen and a number for amount present.
ELISA yields a color change to indicate the presence of the antigen and a generates a number for the amount of antigen present
ELISA yields a color change for presence of antigen and the intensity of the color indicates the amount present
There is a computer printout with the results of the test and the amount present
Any measure whose purpose is to improve health or alter the course of a disease is called
quality of life
medical intervention
medication
philosophy
