H. Ernest Hemphill

Emeritus Associate Professor, Biology and Editor for Bio@SU

Research Interests

DNA sequence and structure; certain temperate bacteriophages of Bacillus subtilis spontaneously delete large fragments of their genomes when they are in the prophage state; current interest is in structure at the deletion breakpoints and in isolation of novel bacterial mutants that alter the deletion frequencies during the phage life cycle
