As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...
A mixture of DNA and proteins—known as "chromatin"—sits inside every cell nucleus as a jumbled puddle of genetic information. As cells prepare to divide during mitosis, the chromatin is condensed into ...
Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...
Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...
