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 ...

But the nucleus isn't just a bag full of ramen ... Even two bits of DNA on totally separate chromosomes can interact in this 3-D web. How these loops and twists are arranged is what lets cells ...

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

This is exceptional because eukaryotic cells (cells with nuclei) usually keep most of their DNA in the cell nucleus, where it is organised into chromosomes. Some of the plasmids that end up in the ...

To fit into the tiny nucleus, DNA gets compacted by being coiled as if on a spool and further compressed into the well-known shape of chromosomes, which we all encountered in a biology textbook.

Researchers have revealed the structural mechanisms of a major DNA repair pathway in human cells. The research, published ...

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

DNA can be cut up and separated, which can form a 'barcode' that is different from one person to the next. Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs.

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 ...

These findings help us better understand the structure and function of our chromosomes ... cell in your body faces when packing its DNA into its tiny nucleus. To achieve this, nature employs ...

so that each new cell’s nucleus gets one chromosome from each pair. The unattached DNA fragments remain in the center of the dividing cell, where they will be randomly pushed into one of the two new ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically ...
