What is the main role of Tris buffer in a DNA solution?

Answer and explanation

Correct answer: Maintaining a stable pH

Tris is a buffer whose main role is to maintain a stable pH in the DNA solution. A stable pH helps protect DNA from damage under excessively acidic or alkaline conditions. Restriction enzymes, not Tris, cut DNA into smaller fragments. Exam tip: When Tris appears in a DNA isolation or storage buffer, associate it primarily with pH buffering.
