During chromosome replication and rna expression, parts the histones remain attached to dna during the passage of the polymerase. describe how this could be relevant for maintaining cell type identity in differentiated tissues. for example, in the lung epithelia, individual cells are continually dying and being replaced over many years of life, and newly made cells must function as lung epithelia.
