WebHistone modifications and the histone code hypothesis In eukaryotic cells, genes are complexed with core histones and other chromosomal proteins in the form of chromatin. The basic repeating unit of chromatin, the nucleosome, includes two copies of each of the four core histones H2A, H2B, H3, and H4 wrapped by 146 bp of DNA. WebWhich of the following is a prediction of the histone code hypothesis? Histone methyltransferases add methyl groups to histone tails. Each histone tail can be modified only once. Only ATP-dependent chromatin remodeling complexes can modify histone tails. Histone deacetylases add acetyl marks to histone tails. This problem has been solved!
