The structure of a cell’s nucleus has long served as a visible clue to whether a cell is healthy or affected by disease.

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 ...

DNA is organized in segments on chromosomes called genes. Humans typically have ... At the center of each cell lies a nucleus, which contains the information the cell needs to do its job.

Centromeres, specialized regions located at the center of chromosomes, are critical for ensuring proper cell division. During ...

This knowledge is crucial for analyzing how DNA structure ... genome feature in the cell nucleus -- and connects them to gene expression patterns. In human cells, chromosomes aren't arranged ...

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.

The latest imaging method from the Broad Institute uncovers structural disruptions in the nucleus associated with progeria at ...

If DNA bridges persist between chromosomes during cell division, chromosomes are abnormally segregated, leading to genetic ...

Save guides, add subjects and pick up where you left off with your BBC account. The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is ...

One hypothesis is that the DNA loops could determine which genes are switched on in the cell. Inside a nucleus, chromosomes jumble together like a game of Twister. This can bring regulatory elements, ...

After a few more cycles of cell division, the DNA excluded from the nucleus likely degrades in the ... but in some cases it’s the biggest chromosome; in other species it’s the smallest one. The genes ...

If you didn’t have them, your DNA molecules would be too big to fit inside your cells ... genes. When the X chromosome is inactivated, it gets folded into a small, dense structure in the ...
