Abstract

During meiosis, in most organisms chromosome pairing and recombination are mechanistically linked, but the nature of their independence is not well understood. In budding yeast, the formation of meiotic DNA double strand breaks (DSBs) is a pre-requisite to both recombination and chromosome pairing. The aim of the study is to determine whether it is DSBs themselves which provide the signal to the cell to commence chromosome pairing or if the DSB forming enzyme Spo11p is required to initiate the signal. This will be done using Spo11p independent DSBs created by site specific endonucleases. We will also set up screen for spo11 mutants which can make DSBs but cannot induce chromosome pairing. Chromosome pairing will be assessed both genetically and cytologically.
