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...
