Repetitive DNA occurs widely, if not universally, among higher organisms. A variety of procedures has been developed or adapted to examine its characteristics and a body of concepts and language has grown up to deal with its complexities. This chapter attempts to summarize this body of knowledge and technique. Owing to human frailty and the real problems of the subject, it tends to emphasize the approaches and conceptual position. The chapter describes techniques for the analysis of repeating DNA sequences by reassociation and a method for the evaluation of rate constants. The purity of the DNA's used in reassociation is critical, as the presence of contaminating proteins and metal ions can markedly alter reassociation results and reproducibility. Metal ions can be removed from DNA by passing it over Chelex 100 (Bio-Rad Labs) that has been neutralized and equilibrated with buffer.
