Scientists have placed another piece in the puzzle of how sexual reproduction shuffles genes while making sure sperm and eggs get the right number of chromosomes. Neil Hunter's laboratory in the UC ...

Meiosis, the process by which haploid products are created from diploid precursors, is central to sexual reproduction. Meiosis can be thought of as a modified mitotic division with notable ...

A research collaboration based in Kumamoto University (Japan) has clarified how homologous chromosome pairing--a process necessary for sperm and egg formation where paternally- and maternally-derived ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

GENETICISTS have identified an enzyme which regulates the production of sperm and egg cells in human reproduction. The discovery furthers our understanding of a process which can often go wrong, ...

Where would we be without meiosis and recombination? A new article describes how proteins called SUMO and ubiquitin and molecular machines called proteasomes play a crucial role in DNA recombination ...

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 ...

Figure 1: Image showing that protein-based artificial kinetochores (magenta) can interact with spindle microtubules (green) in a similar manner to chromosomes (cyan ...
