The structure of DNA varies along its sequence, which can lead to sequence-dependent variations in the fidelity of DNA copying and repair. And because the probability of distinct classes of mutations varies along a DNA sequence, variation that affects fitness will have evolutionary implications, as selection acts on heritable variation.

This Annals volume brings together a broad interdisciplinary group of researchers to explore the impact of increasing understanding of DNA structure, repair, replication, and organization on interrelated subjects ranging from evolution, to dependence of the effect of mutagens on environmental and sequence context, to noncanonical forms of information representation in genomes.
