Histones are basic proteins, and their positive charges allow them to associate with DNA, which is negatively charged. Some histones function as spools for the thread-like DNA to wrap around.

This is the DNA. Dip the glass rod into the tube, slowly rotating it to spool the banana's DNA around the rod. Observe the DNA in the test tube. Write your answers on a separate sheet of paper.

to show that RAD52 proteins form an unexpected spool-like structure composed of two rings of RAD52, each containing 11 copies of protein, that engages all three arms of the "DNA replication fork ...

With all evidence thus far suggesting Bd0055 could be a typical histone protein, the team set out to determine if Bd0055 forms spools for DNA to wrap around. Computer simulations carried out by Shawn ...

In the new study, Spies’ team used cryogenic electron microscopy (CryoEM) to show that RAD52 proteins form an unexpected spool-like structure composed of two rings of RAD52, each containing 11 copies ...

Studies have also have tapped into the nature of DNA’s primary packing material: protein spools called histones around which genomes wind to form nucleosomes. Nucleosomes, which are often compared to ...

Dr. Tsukiyama has discovered that a specific family of proteins helps the most basic units of chromatin — cartwheel-shaped molecular complexes around which DNA spools — slide along DNA to help control ...
