How is all of that DNA packaged so tightly into chromosomes and squeezed into ... The basic repeating structural (and functional) unit of chromatin is the nucleosome, which contains eight histone ...

Chromosomes also play a role in regulating gene expression. The structure and packaging of chromatin can influence which genes are active or silenced in a particular cell type or developmental stage.

The single chromosome displayed here and those ... DNA without all of the proteins that organize it into chromatin. Note how its structure resembles a twisted ladder. Note also that DNA with ...

Thus, in the reconstruction of the four daughter nuclei, two of them contain more chromatin than the other two. The resulting pollen grains, however, look alike. 14. In the somatic mitosis there are ...

How abnormalities in chromosome number are detected to activate this ... such as the organization of chromatin (the structure containing DNA) and the nuclear lamina (a network of proteins supporting ...

This discovery changes how scientists think about chromatin. Instead of being a static structure, chromatin is constantly moving, influencing how genes are read and used by the cell. "In simple ...
