The centromere is necessary for the transport of chromosomes during cell division and, therefore, for the correct transmission of genetic information. Most plants and animals have chromosomes with a ...

New research shows that the male X chromosome is silenced in some types of cancer. Researchers evaluated how a certain gene affects the male X chromosome in cancer cells. Experts explain why these new ...

Two different types of centromeres evolved from a monocentromere, a macro-monocentromere in Cha. luteum and a holocentromere in Chi. japonica. Micrographs show mitotic chromosomes. The centromere is ...

The loss of the Y chromosome in tumour cells is linked to poor outcomes for people with cancer 1, but this genetic alteration might also compromise immune cells that would otherwise fight the disease.

Depending on the setting, the ability of a crucial bacterium in biotechnology—Agrobacterium tumefaciens—to transfer its DNA to a host plant can make it either a pathogen that damages crops or a ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Agrobacterium tumefaciens magnified 15,000 times in an image captured earlier this year with a scanning electron microscope at Iowa State University's Roy J. Carver High Resolution Microscopy Facility ...
