DNA can't explain all inherited biological traits, research shows

Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows. A histone is a protein that provides structural support to a chromosome. In order for very long DNA molecules to fit into the cell nucleus, they wrap around complexes of histone proteins, giving the chromosome a more compact shape. Some variants of histones are associated... [[ This is a content summary only. Visit my website for full links, other content, and more! ]]
