Despite being densely packed to fit into the nucleus, chromosomes storing our genetic information are always in motion. This allows specific regions to come into contact and thereby activate a gene. A ...

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 ...

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 ...

In diagrams and illustrations of cells, DNA is sometimes shown as a mass in the cell's nucleus, like a bowl of ramen noodles. For many years, it's been standard practice to take images of cells that ...

Gene therapy holds the promise of preventing and curing disease by manipulating gene expression within a patient's cells. However, to be effective, the new gene must make it into a cell's nucleus. The ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

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 ...

Almost like a moon in a planet, the exclusome (yellow- green dot) lies in the cytoplasm near the nucleus (blue). Even the remarkably familiar can sometimes yield new discoveries: researchers at ETH ...
