MI-FINAL EXAM Practice Test 2022-2023

Which phrase below best summarizes DNA microarray technology?

• DNA microarray technology is not a diagnostic tool, but more of a confirmation of what is already known regarding a patient.
• By comparing gene expression between a healthy cell and a cancer cell, mutations that regulate cell grown, division, and death can be detected.
• Normal gene expression can only be examined using microarray technology.  Abnormal gene expression must be tested using a different method.

In the microarray, what does the RED color indicate?

• these genes are not expressed or turned off
• these genes are expressed in healthy cells
• these genes are expressed or turned on in cancer
• there are no genes in this cell

What does the GREEN color indicate in DNA microarray?

• these genes are expressed in cancer
• these genes are not expressed in healthy cells
• these genes are not expressed in cancer
• there are no genes in these cells

What would be a good definition of a “medical intervention?”

• a medical device such as a cast or crutch
• any thing that can improve health or alter the course of a disease
• an autopsy to determine cause of death
• a medication you take to cure an illness

The collection, classification, storage, and analysis of biochemical and biological information using computers is called

• restriction endonucleases
• bioinformatics
• medical interventions
• all of the above

What is BLAST?

• a way to scan DNA to see if there is a mutation
• a test that uses serial dilution to compare the level of pathogenic bacteria in various patients
• another name for ELISA
• a huge database used to search and compare unknown biological sequence information

When you copied and pasted the pathogenic DNA from a patient into BLAST, you obtained

• a list of patients who have the same diseases in nearby areas
• a list of antibiotics needed to treat the pathogen
• a list of possible disease causing agents listed
• a list of famous people who have had this disease in the past

What process goes out of control in cancer cells that is responsible for cell division?

• mitosis
• photosynthesis
• cellular respiration
• meiosis

this is a series of x-rays from many different angles

• X-Ray
• CT Scan
• MRI
• Bone Scan

this test uses powerful magnets and radio waves

• X-Ray
• CT Scan
• MRI
• Bone Scan
