Meiotic recombination is a specialised process in which programmed DNA double-strand breaks initiate the exchange of genetic material between homologous chromosomes. This exchange forms crossovers ...

In the 1980s, scientists knew little about the X and Y chromosomes. What they did understand was that every cell in the body contains 23 pairs of chromosomes. Each of these pairs is similar, except ...

The Y chromosome is often described as the smallest and most fragile chromosome in mammals. Over millions of years, it has ...

The above representative microscope images showcase ultra-fine bridges, a kind of abnormal link between chromosomes that causes catastrophic genetic instability. These bridges, composed of entangled ...

Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic ...

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 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 ...

Research on recombination, which blends DNA from different sources to create new DNA sequences, was one small step for man ...
