PLTW MEDICAL INTERVENTIONS UNIT
1 EXAM QUESTIONS AND ANSWERS.
VERIFIED 2026.
Medical Intervention - ANS Any measure whose purpose is to improve health or alter the
course of disease
Medical interventions help maintain health and homeostasis in the body.
Pathogen - ANS A specific causative agent of disease
Outbreak - ANS A sudden rise in the incidence of a disease
Patient Symptoms/Risk Factors Organizer - ANS Chart detailing information about patients'
symptoms and any part of their lifestyle or background that may increase their risk for certain
diseases.
Primer - ANS Complimentary DNA segment that allows the enzyme to bind to the DNA for
DNA replication.
Bioinformatics - ANS The collection, classification, storage, and analysis of biochemical and
biological information using computers especially as applied in molecular genetics and
genomics.

, Genome - ANS An organisms genetic material
PCR Amplification - ANS Melt: Highest temp, separates strands
Anneal: Lowest temp, primers attach
Extend: Medium temp, DNA replicates (Polymerase)
Final Extension: Ten minutes at medium temp, ensure DNA has finished replicating
DNA Sequencing - ANS The DNA is placed in order by size (smallest to largest) using gel
electrophoresis or a similar method. It is then tagged by color (using fluorescent markers on the
stoppers of the DNA) as to what nucleotide it represents. The nucleotides in size order are the
DNA sequence. The bacteria can be identified using BLAST
Solute - ANS Substance dissolved in another substance
Solvent - ANS A substance, usually a liquid, in which another substance is dissolved.
Solution - ANS A homogeneous mixture of two or more substances. They may be in any state
of matter.
Concentration - ANS The amount of a specified substance in a unit amount of another
substance
Antibody - ANS An antigen-binding immunoglobulin, produced by B cells, that functions as
the effector in an immune response
Antigen - ANS A foreign macromolecule that does not belong to the host organism and elicits
an immune response
