Abstract

The principal concern from the forensic science standpoint is that many of the environmentally induced lesions are expected to be inhibitory toward DNA-polymerase mediated primer extension and may result in amplification, and hence DNA typing, failure. To understand these processes, it is beneficial to consider the mechanisms by which DNA damage may take place. The ability to detect DNA polymorphisms using molecular genetic techniques has revolutionized the forensic analysis of biological evidence. The major pathways involved in the correction of DNA damage include base excision repair (BER), nucleotide excision repair (NER), single strand break repair (SSBR), mismatch repair (MMR), direct reversal with the photoreactivation activity of photolyases, by recombination and rejoining pathways, or through tolerance with translesion synthesis (TLS). This chapter explores the types of DNA damage that predominate in physiological stains deposited at a crime scene.
