Xkid chromokinesin is required for chromosome alignment on the metaphase plate of spindles formed in Xenopus laevis egg extracts. We have investigated the role of Xkid in Xenopus oocyte meiotic ...

During egg and sperm production, the two copies of a duplicated chromosome must be bound together until it is time for their separation. A protein that protects this chromosomal glue has now been ...

Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell ...

In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...

During sexual reproduction, haploid gametes (i.e. eggs and sperm) are generated from diploid precursors through the specialized cell division of meiosis. Meiosis reduces ploidy by following one round ...

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 ...

In order to control various biological processes, cells are able to selectively alter properties of their proteins, such as their lifespan, activity level, binding partners, or localization of the ...
