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 ...

Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in ...

An international research team led by Baylor College of Medicine and The University of Osaka have found a way to resume sperm ...

There is a high unmet need for accessible, affordable, and high-quality fertility care, as approximately 1 in 6 people are affected by infertility worldwide. While meiotic failure is a major cause of ...

Researchers at Oregon Health & Science University (OHSU) have developed a remarkable new way for making human body cells ...

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 ...

Chromosomes begin to condense, taking on the form that they are usually depicted in: four arms connected at a point. Each chromosome is, at this time, actually two identical copies. Each copy is ...

Researchers are examining how the processes that regulate gene expression and chromosome behaviors can lead to health issues, including cancer, birth defects, miscarriage, and infertility. Researchers ...

Interphase is the period between cell divisions. During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating bases attach to the unzipped strands. The ...
