What is the most correct role of a lysis buffer?

Answer and explanation

Correct answer: Opening cells and releasing DNA

The governing concept is cell lysis, the first major step in making intracellular DNA accessible. A lysis buffer contains chemicals that disrupt the plasma membrane and, for many samples, the nuclear membrane as well. Depending on its composition, it can also denature proteins, dissolve membrane lipids, and inhibit nucleases that might otherwise degrade DNA. Thus option C is correct: opening the cells releases DNA into the surrounding solution so it can subsequently be separated and purified. DNA staining is a later detection procedure. Turning a sample into a plant or converting protein into glucose is unrelated to the chemical purpose of a lysis buffer.
