Mutagenesis assays primarily assess changes to which cellular component?

Explanation:
Mutagenesis assays are designed to detect heritable changes in the genetic material. The core focus is the DNA itself—the molecule that stores and transmits genetic information. When a mutagen causes a change in DNA, such as a base substitution, insertion, deletion, or larger chromosomal alteration, this can lead to mutations that the assay reveals. RNA transcripts depend on the DNA template and may change as a downstream effect, but they are not the primary target of mutagenesis testing. Similarly, cell membrane lipids relate to membrane integrity rather than genetic alterations. So, the component most directly assessed by mutagenesis assays is the genetic material.
