DNA Structure and Replication

ID #2087

Why do histones have many alpha helices? And what does "core histones" mean? Is it different from just saying histone?


Alpha helices are good for protein/DNA interactions, which is just the kind of thing we want to happen with our chromatin and histones.

 

Core histones are the histones that have the DNA wrapped around them. So it's not the same thing as just saying histone. H1 is a histone, but isn't part of the core.
