When a woman becomes pregnant, the outcome of that pregnancy depends on many things — including a crucial event that happened ...
A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...
What do a human, a rose, and a bacterium have in common? Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic acid or ...
The Atlas blue butterfly, with a record-breaking 229 pairs of chromosomes, is helping scientists unravel mysteries of ...

DNA sequence once overlooked as ‘junk’ found to drive human chromosome fusions
Leonardo Gomes de Lima, Ph.D., a postdoctoral associate in the Gerton Lab, led the research. The findings show how these chromosome fusions form, why they remain stable, and how repetitive DNA, once ...
There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...
Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Scientists identify fusion point of Robertsonian chromosomes, hinting at how chromosomes evolve
In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists.
The human Y chromosome, responsible for determining male sex, finally has gotten an end-to-end examination. The Y chromosome is the smallest of the human chromosomes. “In the old time, people thought ...
The central area of chromosomes, the centromere, contains DNA that has survived largely unchanged for hundreds of thousands of years, researchers at UC Davis and the Lawrence Berkeley Laboratory have ...
Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter discovered a new property of the molecular motors that shape our chromosomes. While six years ago ...
