A chromosome is a single, long molecule of DNA. These highly organized structures store genetic information in living organisms. Small sections of the chromosome, called genes, code for the RNA and ...

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 ...

For the first time, researchers see how proteins grab loops of DNA and bundle them for cell division. The discovery also hints at how the genome folds to regulate gene expression. A human cell carries ...

Chromosomes carry our basic genetic material. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Your DNA blueprint (genome) doesn't exist as one ...

Our DNA is arranged into chromosomes that carry a kind of protective shield at their ends, called telomeres. These protective ...

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 ...

Researchers from Skoltech, the University of Potsdam, and the Massachusetts Institute of Technology have discovered a ...

Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes, ...

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 ...

An illustration shows the process of cell division, which involves chromosome pairs swapping some of their genetic data. frentusha/iStock Variety is the spice of life—especially when it comes to ...

A human cell carries in its nucleus two meters of spiraling DNA, split up among the 46 slender, double-helical molecules that are its chromosomes. Most of the time, that DNA looks like a tangled ball ...
