In short, DNA is a complex molecule that consists of many components ... this highly compacted DNA is then arranged into structures called chromosomes. Chromosomes take different shapes in ...
How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...
Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...
They worked out that in a DNA molecule: there are two strands the ... The DNA coils into structures called chromosomes. The chromosomes are found in the nucleus of each cell.
The flowerpot snake, one of the world's smallest snakes, has some unusual distinctions. Also known as the Brahminy blind ...
For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

So, it's very easy to see,” she said. To zoom in on changes in chromosome organization during meiosis, the researchers used nuclear membrane and DNA damage protein stains to track nuclear behavior.
This coiling causes the chromosome to resemble a spring. Chromatin refers to proteins that help organize the long DNA molecule. The protein shown here supports and organizes small loops of DNA.
In the multilayer chromosome model ... internally crosslinked by the covalent backbone of a single DNA molecule. The ...
Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a ...
When bacterial DNA is labeled with radioactive atoms, it takes its own picture. Autoradiographs reveal that the bacterial chromosome is a single very long DNA molecule and show how it is duplicated ...
