Aseptic technique protects against what?

Answer and explanation

Correct answer: Unwanted microbes

Aseptic technique consists of practices that prevent unwanted microorganisms from entering cultures, media, containers, instruments, and samples. It is therefore used to protect an experiment from microbial contamination, making option A correct. A sterile working area, properly sterilized equipment, careful handling of containers, and minimizing exposure reduce the chance that bacteria or fungi from the environment will enter the culture. Aseptic technique does not protect a proper plasmid, a correct selectable marker, or an expected electrophoresis band; those are experimental components or results rather than contaminants. Reliable transformation and expression conclusions require both aseptic handling and suitable controls.
