The Portuguese island of Madeira is home to six different chromosomal races of mice, each with dramatically reduced diploid chromosome numbers compared to mice elsewhere. This striking diversity, ...

Since the 1800s, scientists have noted configuration of centromeres, a special chromosomal region that is vital for cell division, in the nucleus. Up until this point, however, the determining ...

Centromeres are curious structures. These specially organized chromosomal regions are best known for their unique and critical role in cell division, in which they are well understood to serve as the ...

Six years ago, when Glennis Logsdon was a graduate student, everyone assumed that centromeres had conserved sequences and structures given their essential role in divvying up genetic material. “We had ...
