What is the purpose of enzymes in DNA fingerprinting?

Back

Enzymes are added to cut the DNA into fragments for analysis.

Front

What is gel electrophoresis?

Back

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

Front

How does gel electrophoresis work?

Back

DNA fragments are placed in a gel and an electric current is applied, causing the fragments to move; smaller fragments move faster than larger ones.

A unique pattern of DNA fragments that can be used to identify an individual.

Front

Why is DNA fingerprinting important in forensic science?

Back

It helps to match DNA found at crime scenes with suspects.

Front

What is the significance of the paternity test in DNA fingerprinting?

Back

It determines biological relationships by comparing DNA samples.

Front

What does it mean if two DNA samples match?

Back

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

What are restriction enzymes?

Back

Proteins that cut DNA at specific sequences, used in DNA fingerprinting.
