Front

What is the process of collecting DNA from the nucleus of a cell?

Back

DNA extraction

Front

What is the role of restriction enzymes in DNA analysis?

Back

To cut the DNA into fragments

Front

What technique is used to separate DNA fragments by size?

Back

Gel electrophoresis

Front

What is the purpose of DNA fingerprinting?

Back

To identify individuals based on their unique DNA patterns.

Front

What is the significance of the bands seen in a DNA fingerprint?

Back

They represent different DNA fragments that can be compared between samples.

Front

How does gel electrophoresis work?

Back

It uses an electric field to move DNA fragments through a gel matrix, separating them by size.

Front

What is the first step in DNA fingerprinting?

Back

DNA extraction from a sample.

Front

What type of sample can be used for DNA fingerprinting?

Back

Blood, saliva, hair, or any tissue containing cells.

Front

What is the function of a DNA ladder in gel electrophoresis?

Back

To provide a size reference for comparing DNA fragment lengths.
