Gene Duplication: DNA process that lead to duplicated genes.

We will discuss the molecular mechanisms that are responsible for the duplication of genetic material.
While there are numerous mechanisms and nuanced details that lead to slight variations of these processes, the general mechanisms can be grouped into 4 categories.
1) Unequal Crossing Over :: Jeff Hunter
2) Duplicative Transposition of DNA (for an exhaustive review see Paques) :: Mischka Moechtar
3) Retrotransposition (for a short note see Broslus) :: Kaleigh Ahlquist
4) Polyploidization :: Sean Maden
4 Students will volunteer to present a 15 - 20 minute "chalk talk" explanation of these processes.
