Chromosome segregation and site-specific recombination are central processes in bacterial cell division and genome maintenance. The orchestration of these events ensures that circular chromosomes are ...

When a woman becomes pregnant, the outcome of that pregnancy depends on many things—including a crucial event that happened while she was still growing inside her own mother's womb. It depends on the ...

The biological necessity of the Y chromosome is undergoing a fundamental reassessment as evidence confirms its disappearance in specific mammalian lineages. While this chromosome has served as the ...

A team of Chinese researchers led by Prof. GAO Caixia from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences has developed two new genome editing technologies, ...

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 ...

When a woman becomes pregnant, the outcome of that pregnancy depends on many things - including a crucial event that happened while she was still growing inside her own mother's womb. It depends on ...

Sex is determined in a variety of different ways throughout the animal kingdom. In mammals, it is determined genetically, not by temperature, as it can be in reptiles. Typically, females have two X ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...
