Chromosome Segregation During Gametogenesis

Faithful DNA repair and establishment of crossovers are essential for accurate segregation of the homologous chromosomes in the gametes and to preserve genome integrity across generations.

Nicola Silva’s team is interested in dissecting the pathways regulating these processes by studying several factors involved in the formation and repair of meiotic breaks, as well as by identifying novel proteins that promote recombination and licensing of chromosome synapsis, using Caenorhabditis elegans as model system.
