For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...
Scientists have uncovered how brewer’s yeast developed its unusually tiny centromeres, the DNA regions that guide chromosome ...
Researchers created artificial kinetochore structures that reduce chromosome separation errors during meiosis in aging egg cells. By lowering microtubule pulling force, the approach helped maintain ...
Genomic analysis of three Neanderthals shows unusually high modern human DNA on the X chromosome offering clues about ...
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...
A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery-how "selfish chromosomes" cheat the rules of genetic inheritance.
A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...
This important study demonstrates that a peri-nuclear actomyosin network, present in some types of human cells, facilitates kinetochore-spindle attachment of chromosomes in unfavorable locations - ...
A study explains how broken DNA during cell division can trigger chromoanasynthesis when two repair pathways combine, causing ...
The Iñupiat people of Alaska have long said that bowhead whales live two human lifetimes. That oral knowledge turned out to ...
The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes.
There is something like less than one chance in 10 billion that this kind of thing could occur," said one expert.
