A Technique That Separates a Readable Pattern of DNA Fragments

Question

A technique that separates a readable pattern of DNA fragments is
A)genetic engineering.
B)biotechnology.
C)recombinant DNA.
D)gel electrophoresis.
E)gene probes.

Accepted Answer

Gel electrophoresis is a technique used to separate DNA fragments based on their size and charge. The DNA fragments are placed in a gel and an electric current is applied, causing the fragments to migrate towards the positive electrode. Smaller fragments move faster and farther than larger fragments, allowing for separation and visualization of a readable pattern. A ladder or standard with known fragment sizes is commonly used to determine the size of unknown fragments.
