PLTW MI: Unit 1 Review

Front

What is the role of the enzyme in the ELISA test?

Back

The enzyme causes the substrate to change, resulting in a color change.

Front

What are medical interventions in the context of biotechnology?

Back

Medical interventions include techniques like PCR, BLAST, and DNA sequencing that are used to diagnose or treat diseases.

Front

What is the primary cause of an outbreak?

Back

Pathogens are most responsible for outbreaks.

Front

How do vaccines function in the immune system?

Back

Vaccines activate the adaptive immune response against an antigen so that the immune system will 'remember' the pathogen.

Front

What are primers in PCR reactions made of?

Back

Primers in PCR reactions are made up of single stranded DNA.

Front

Define ELISA test.

Back

ELISA (Enzyme-Linked Immunosorbent Assay) is a test used to detect the presence of antibodies or antigens in a sample.

Front

What is PCR and its purpose?

Back

PCR (Polymerase Chain Reaction) is a technique used to amplify small segments of DNA for analysis.

Front

What is the function of antibodies in the immune response?

Back

Antibodies are proteins produced by the immune system to identify and neutralize pathogens.

Front

What is the difference between innate and adaptive immunity?

Back

Innate immunity is the body's first line of defense, while adaptive immunity develops a specific response to pathogens.

Front

What is the significance of DNA sequencing?

Back

DNA sequencing determines the exact sequence of nucleotides in a DNA molecule, which is crucial for genetic analysis.
