Rethinking Models of DNA Organization in Micrometer‐Sized Chromosomes from the Perspective of the Nanoproperties of Chromatin ...

Chromosomes are tightly coiled structures ... and G to “bases,” which are part of the structure of DNA. Strings of these letters make up your complex genetic code. If you think of yourself ...

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

RNA sometimes forms a secondary double helix structure, but only intermittently. DNA is a much longer polymer than RNA. A chromosome, for example, is a single, long DNA molecule, which would be ...

DNA is packed into chromosomes, which form genetic information ... B-DNA is the most common form of DNA and has a right-handed double helix structure. A-DNA forms in a shorter, right-handed ...

This “junk DNA” is comprised of highly repetitive ... has been pushed a bit further toward the tip of the Y chromosome. We now know the structure of the centromere (a region of the chromosome ...

2) Identification of the mechanisms that contribute to differences in meiotic chromosome structure in male and female meiosis. In both mitosis and meiosis DNA needs to be organized into chromosomes.

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.

How was it possible that DNA fragments of ancient chromosomes survived for over 50,000 years with their three-dimensional structure intact? The team found that the chromosome fossils looked ...

These findings help us better understand the structure and function of our chromosomes. They also provide insight into how disruption of twisted DNA looping can affect health -- for instance ...
