pulverized chromosomes, chromatids breaks, gaps or exchanges, in metaphases. From each cell monolayer, 50 metaphases were at random analysed, but in those samples in which this number was not reached, ...

The last few years have provided us with a new level of understanding of how chromosomes are replicated, segregated and read - and how their 3D organisation influences expression of individual genes ...

We analysed between 50 and 100 metaphases for each clone, and scored chromosomes as positive if a signal doublet could be detected on both sister chromatids of the respective chromosome.

Cephalopods may have the oldest sex chromosomes of any animal, according to a new discovery in the octopus genome. That's a big deal given that scientists didn't know until now if these oddball ...

Dating back 480 million years, octopuses have one of the oldest known sex chromosomes, according to a new study published in Current Biology. The study unveils that octopuses determine their sex ...

Researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus ...
