Research reveals that five DNA letters can switch chromatin between fluid and solid-like states, influencing gene ...
DNA inside human cells is not just floating around freely. It is tightly wrapped around small proteins, forming a long chain.
The nuclei of most human cells contains the entire genome, which would have a length of about six feet if it was fully extended. So this DNA has to be carefully compacted in cells, while still ...
A single cell contains 2-3 meters of DNA, meaning that the only way to store it is to package it into tight coils. The solution is chromatin: a complex of DNA wrapped around proteins called histones.
