Whole genome cloning and expression of Treponema pallidum open reading frames

Lead Institution
Baylor College of Medicine
Principal Investigator
Timothy Palzkill
Project type
Exploratory Research
Treponema pallidum is a spirochete bacterium and is the causitive agent of syphilis. The complete genome sequence of T. pallidum is known. The organism has a genome size of 1.1 Mb and encodes 1031…

Excited states of DNA hairpins

Lead Institution
Northwestern University
Principal Investigator
George Schatz
Project type
