With a few exceptions, eukaryotic chromosomes have a single centromere that ensures their accurate segregation during mitosis. Chromosomes that lack centromeres segregate randomly during mitosis ...

Biologists in Europe and the U.S. have pinpointed a secret that powers the human body’s gene replicating ability. These areas ...

In a recent paper published in the journal Genome Research, experts described the chromatin arrangement in the genomes of two ...

"For that to happen, each chromosome has a centromere. In plants, centromeres control chromosome partitioning with the help of a molecule called DDM1." Martienssen discovered DDM1 in 1993 with a ...

Human chromosomes can be differentiated from one another under a microscope by their lengths and by the position of the centromere.

A study described the three-dimensional architecture of turtle genomes, which fold in a configuration unlike any other animal observed so far.

which latches onto the chromosome at a place called the centromere — a region containing highly repetitive DNA sequences. Comparing the sequences of these repeats revealed where mutations have ...

New research finds that turtle genomes show a chromatin arrangement that hasn't been observed in other organisms.

Researchers from Cold Spring Harbor Laboratory studied Arabidopsis thaliana to understand how plants maintain chromosome stability when the critical molecule DDM1 is absent. They discovered that ...

In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.
