Chromosomal DNA The DNA of bacterial cells is found loose in the cytoplasm. It is called chromosomal DNA and is not contained within a nucleus. Plasmid DNA Bacteria also have small, closed-circles of ...

Research reveals that five DNA letters can switch chromatin between fluid and solid-like states, influencing gene ...

A new DNA structure inside human cells known as the “i-motif”, has been identified by scientists. This form resembles a twisted “knot” of DNA, instead of the well-known double helix first described by ...

Structure of DNA rewritten as scientists find genetic 'towers' in human cells Scientists discover that the twisting, ladder-like structure of our genes can sometimes have two extra arms, forming a ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

In cancer, a lot of biology goes awry: Genes mutate, molecular processes change dramatically, and cells proliferate uncontrollably to form entirely new tissues that we call tumors. Multiple things go ...

A team of researchers has generated one of the most detailed 3D maps of human chromosomes, cataloging over 140,000 DNA looping interactions.

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

Researchers have identified the specific structural loops in G-quadruplex DNA that allow it to act as a chaperone, preventing ...
