It describes how random assortments and recombination of gene segments during B cell differentiation, alongside mechanisms for TCRs, contribute to this variability. Notably, αβ T cells exhibit high diversity from the CDR3 region, while γδ T cells have a smaller repertoire.

As you already know, even minor changes in DNA sequence, such as point mutations can sometimes have far-reaching consequences. Likewise, unrepaired damage caused by radiation, environmental chemicals or even normal cellular chemistry can interfere with the accurate transmission of information in DNA.

It highlights the Ames test for detecting mutagenic chemicals in organisms, the impact of ionizing radiation on DNA, and the role of transposons (or "jumping genes") in generating mutations by relocating within the genome.
