Molecular Biologist Nancy Kleckner to Present Cosloy – Blank Lecture, Oct. 23

Dr. Nancy Kleckner

Dr. Nancy Kleckner, Herchel Smith Professor of Molecular Biology at Harvard University, will present the 9th Annual Sharon Cosloy – Edward Blank Lecture at The City College of New York 4 p.m. Thursday, October 23, in NAC 0/201. Her talk is titled “Chromosome Dynamics from Bacteria to Mammalian Cells.” The event is free and open to the public. Please RSVP to 212.650.8499 or

Professor Kleckner earned her undergraduate degree from Harvard and a PhD from the Massachusetts Institute of Technology (MIT) for work done with Ethan Signer on the replication of DNA in a bacterial virus. During her postdoctoral work with David Botstein at MIT, she showed that bacteria possessed segments of DNA that could ‘jump around’ from site to site on the chromosome, a process known as DNA transposition.

A member of the Harvard faculty since 1977, Dr. Kleckner has conducted a series of genetic experiments there. She was able to elucidate the cut-and-paste nature of transposition. Her work also included the first identification of a small anti-sense RNA that inhibited protein translation, of IS10 transposase, and the purification of proteins responsible for transposition and elucidation of how they worked.
