Luca Comai and Michele Igo Receive College of Biological Sciences Faculty Teaching Award

The College of Biological Sciences Faculty Teaching Award has two recipients for the 2016-2017 year. Luca Comai, professor of plant biology, and Michele Igo, professor and vice chair of microbiology and molecular genetics, are recognized for their excellence in teaching through enthusiasm and effectiveness of instruction, application of technology and innovation in the classroom, and mentorship and motivation of students.

Close-Up View of DNA Replication Yields Surprises

For the first time scientists have been able to watch individual steps in the replication of a single DNA molecule, with some surprising findings. For one thing, there’s a lot more randomness at work than has been thought. “It’s a different way of thinking about replication that raises new questions,” said Stephen Kowalczykowski, distinguished professor in microbiology and molecular genetics at the University of California, Davis, and at the UC Davis Comprehensive Cancer Center. The work is published June 15 in the journal Cell with co-authors James Graham, postdoctoral researcher at UC Davis, and Kenneth Marians, Sloan Kettering Cancer Center.

New Steps in the Meiosis Chromosome Dance

Where would we be without meiosis and recombination? For a start, none of us sexually reproducing organisms would be here, because that’s how sperm and eggs are made. And when meiosis doesn’t work properly, it can lead to infertility, miscarriage, birth defects and developmental disorders. Neil Hunter’s laboratory at the UC Davis College of Biological Sciences is teasing out the complex details of how meiosis works.
