Why is wearing gloves important in DNA isolation?

Answer and explanation

Correct answer: To prevent contamination of the sample by DNA, microbes, and nucleases from hands

Skin on the hands may carry human DNA, microorganisms, and nucleases—enzymes that can degrade DNA. Gloves prevent these materials from entering the sample, helping to obtain purer, protected DNA. DNA staining is done separately with appropriate dyes; gloves do not colour DNA. Exam tip: For preventing contamination during DNA isolation, remember gloves, clean tools, and nuclease-free materials.
