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, ...

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 ...

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 ...

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 ...

For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

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 ...

Human DNA, which is approximately two meters in length, is organized into a compact, thread-like structure known as the chromatin, so it could fit into the nucleus, a tiny sphere that’s only about six ...

Every cell that produces eggs or sperm must first sort its chromosomes into matching pairs, lining up each one with its homologous partner before they exchange genetic material. According to the ...
