13. NC EOC Review: DNA Fingerprinting & Gel Electrophoresis RB

Front

What is DNA Fingerprinting?

Back

A technique used to identify individuals based on their unique DNA profiles.

Front

What is Gel Electrophoresis?

Back

A laboratory method used to separate DNA fragments based on their size.

Front

What are restriction enzymes?

Back

Proteins that cut DNA at specific sequences, creating fragments for analysis.

Front

How do lighter-weight DNA fragments behave in Gel Electrophoresis?

Back

They move faster and are found closer to the bottom of the gel.

Front

What is the purpose of DNA extraction?

Back

To isolate DNA from cells for analysis.

Front

What is the significance of DNA profiling in forensic science?

Back

It helps to match DNA samples from crime scenes to suspects.

Front

What is the role of a DNA ladder in Gel Electrophoresis?

Back

To provide a reference for determining the size of DNA fragments.

Front

What does it mean if two DNA samples have matching bands in Gel Electrophoresis?

Back

It indicates that the samples may come from the same individual.

Front

What is the first step in DNA fingerprinting?

Back

Collecting a sample of DNA from the individual.

Front

What is the function of a loading dye in Gel Electrophoresis?

Back

To visualize the DNA samples and track their movement through the gel.
