Sometimes the best way to understand a biological process is to disrupt the normal process and analyze the result. That’s why Sloan Kettering Institute (SKI) researchers used a strain of mutant mice ...

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 ...

In the beginning, you were just some genetic material. In order to make you, your biological mom and dad both had to participate in an effort to pitch in one gamete each — a sperm cell and an egg cell ...

Meiosis is a specialized type of cell division in which two rounds of chromosome segregation follow a single round of DNA replication. In diploid organisms, meiosis generates gametes with a haploid ...

Meiosis is a highly coordinated cell division, which generates four haploid reproductive cells required for sexual reproduction. Meiosis involves one round of DNA replication and two nuclear divisions ...

Researchers have identified an enzyme essential for the process of male meiosis, the type of cell division that produces sperm. The protein, SKP1, controls one of the key transitions in meiosis.

More than one-sixth of adults around the world experience infertility in their lifetime. There is a high unmet need not only for increased access to affordable, high-quality fertility care for those ...
