Japanese researchers used CRISPR-Cas9 to remove the extra chromosome 21 from cells in a lab. It’s a real breakthrough — but ...

Repetitive DNA and the D1 protein help matching fruit fly chromosomes recognize one another before eggs form.

Around 7,000 years ago, the genetic diversity of human males suddenly dropped across parts of Africa, Europe,and Asia. Scientists studying the DNA, more specifically Y chromosome, and found evidence ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study, ...

Inside each human cell, about 2 meters (6.6 feet) of genomic DNA must be accurately copied and equally transmitted to two daughter cells during cell division. To achieve this, the copied DNA is ...

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 ...

New research into mitotic chromosomes has found that they are covered in a liquid-like coating that could allow them to bounce off one another, like bumper cars, protecting them from being damaged ...

A record player-like microscope and computer simulations solve a longtime mystery, showing that metal ions bridge DNA strands ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

The body cells of humans and animals contain a double set of chromosomes. One half of the genetic material comes from the mother, the other stems from the father. During the formation of sperm or egg ...

A new study conducted on roundworms finds that a common plastic ingredient causes breaks in DNA strands, resulting in egg cells with the wrong number of chromosomes. Monica Colaiácovo of Harvard ...
