For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

In the 1930s, Muller was surprised to note that telomeres were strangely resistant to mutagenic X-rays. Why are the unique properties of these chromosomal "end caps" so important? Thus, in her ...

Chromosomes occupy specific regions of a nucleus, called "chromosome territories." These subdomains might be doing much more than just keeping everything organized. Determining how chromosomes are ...

Many of us are familiar with typical diagrams of a chromosome, which is sometimes depicted like a stubby X. While that picture may resemble what is seen after some chromosome staining methods, in the ...

Researchers have discovered that a worm commonly used in the study of biology uses a set of proteins unlike those seen in other studied organisms to protect the ends of its DNA. University of Michigan ...

Researchers from the University of Tennessee Health Science Center have made a foundational discovery about chromosome biology through their work on the first-ever human pangenome reference. Published ...

PHILADELPHIA — Women and men sometimes do things differently, right down to divvying up their genetic legacies. This divvying up is known as meiosis, a process that cuts the number of chromosomes in ...

Geneticists say they've built a working yeast chromosome from the bottom up for the first time — a feat that could open the way for custom-made biofactories that churn out fuels and pharmaceuticals.
