Keith & Russ talk with P. Shing Ho, Professor & Chair of the Department of Biochemistry & Molecular Biology at Colorado State University. Shing is a structural biologist, and he explains how the function ofDNA or protein molecules can be altered if there's a slight change in the molecular structure. He also talks about discovering in 1979 how halogens inserted into DNA caused the DNA strands to split into a 4-stranded helical pattern.
