A cell's DNA must be packaged in a way that allows it to be easily stored within a nucleus, but also easily accessed for transcription. Specific structural features allow for certain genes to be stored and others to be transcribed, or expressed, simultaneously. Match each name and description to the structures in the diagram.

A cell's DNA must be packaged in a way that allows it to be easily stored within a nucleus, but also easily accessed for transcription. Specific structural features allow for certain genes to be stored and others to be transcribed, or expressed, simultaneously. Match each name and description to the structures in the diagram. Answer Bank changes to these proteins can alter gene expression nucleosome formed from repeating nucleosomes loops and scaffold chromosome exist in pairs in cell nucleus basic unit of DNA storage histones
For the DNA, the nucleus which is associated with histone proteins, to be transcribed, the DNA has to become accessible. The process changes the state of chromatin and releases the DNA for transcription.
