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 ...

In the choreography of meiosis—the process responsible for sex cell division in all eukaryotic life—the pairing of homologous chromosomes (homologs) is essential. Errors in this process can lead to an ...

Meiosis produces sperm and eggs with exactly half the chromosome number of the individual producing the gametes. To ensure that each gamete has one copy of each chromosome pair, the diploid cell ...

All cells arise from other cells through the process of cell division. Meiosis is a specialized form of cell division that produces reproductive cells, such as plant and fungal spores and sperm and ...

Investigators have employed mutant mice to study how the accumulation of genetic errors is managed during egg and sperm formation. Sometimes the best way to understand a biological process is to ...

The biological research of UC Santa Cruz’s Needhi Bhalla to determine the molecular motions at the heart of heredity has yielded a new discovery: The proper transfer of genetic materials depends on ...

Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. The cells involved with human reproduction, however, carry only half after division occurs. In ...

Francisco Mendez Diaz is in the Department of Cellular and Molecular Medicine, University of California San Diego, La Jolla, California 92093, USA. Kevin D. Corbett is in the Department of Cellular ...

As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from asexual to ...

A team of scientists at the University of Seville has identified an essential process that protects DNA integrity in reproductive cells, providing new clues about how organisms avoid genetic defects ...
