Question

Gel electrophoresis is used in DNA analysis to:

A) Amplify DNA fragments of varying lengths.
B) Analyze DNA fragments of varying lengths.
C) Separate DNA fragments of varying lengths.
D) Grow DNA fragments of varying lengths.

Answer 1

Gel electrophoresis is a technique used to separate DNA fragments of different sizes.

Step-by-step explanation:

Gel electrophoresis is a technique used to separate DNA fragments of different sizes. It involves loading DNA onto a gel made of agarose or polyacrylamide, and applying an electric field. The DNA molecules migrate through the gel from the negative electrode to the positive electrode based on their size. After the separation, DNA fragments of different lengths can be visualized using a specific dye, and the resulting stained gel shows bands that correspond to DNA molecules of different sizes.
