Researchers have clarified how homologous chromosome pairing -- a process necessary for sperm and egg formation where paternally- and maternally-derived chromosomes match and exchange genetic ...

Homologous chromosome pairing is a process where maternal and paternal chromosomes of the same type are aligned, resulting in a partial exchange of genetic information through meiotic recombination.

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub. Its main purpose is to provide the ...

Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...
