Variations in the properties of arabica coffee, such as in taste, caffeine content and disease resistance, are determined by chromosome mutations, according to a recent study. But are these findings ...

Researchers at the University of California San Diego (UCSD) have demonstrated an intriguing new variation on the CRISPR gene-editing system, which involves fixing a mutation on one chromosome by ...

Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

An international study has identified more than 50 genes on the X chromosome in which mutations may cause poor sperm production. Nearly half of all men with low or zero sperm count have no medical ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...
