## Abstract **Background** Slk19 is a coiledโcoil protein, which locates to the kinetochores of __S. cerevisiae__. Most cells lacking Slk19 undergo incomplete meiosis and form dyads during sporulation. Endogenous chromosomes appeared to be predominantly divided in an equational manner during single
## Abstract Kinetochores can form and be maintained on DNA sequences that are normally nonโcentromeric. The existence of these soโcalled neoโcentromeres has posed the problem as to the nature of the epigenetic mechanisms that maintain the centromere. Here we highlight results that indicate that the
Meiosis is too complex to have arisen at once full blown and a stepwise scheme is proposed for its evolution, where each step is believed to have provided an immediate selective advantage: (1) The first step in this tentative sequence is the development of a haploidization process by means of a rapi
