Research Description

Following his early corn genetics studies on the genetic effects of ionizing radiation and a cytogenetic analysis that revealed an unexpectedly high frequency of sister strand crossing over in meiosis, Drew made a radical change in his experimental procedures.  His pioneering work adapting electrophoresis for use in genetic studies resulted in the identification and isolation of a protein as the product of a single gene; it was the first such case in maize.  He presented the first evidence for allelic isozymes and demostrated the existence of "hybrid" enzymes, formed by dimerization of protein subunits produced by different alleles of the E1 esterase system.
