how are the epigenetic marks of a particular chromatin state preserved during cell division? select all that apply. group of answer choices parental, marked h2a-h2b dimers stay associated with strands after replication and recruit new h3-h4 tetramers. h2a-h2b dimers and h3-h4 tetramers come off during replication and assemble with unmarked histones. these new octamers then rebind to the newly replicated dna to form nucleosomes. parental, marked h3-h4 tetramers stay associated with strands after replication and recruit new h2a-h2b dimers. histone chaperones make sure that at least one component of each new nucleosome contains the correct modifications.. epigenetic markers are spread from old histones to new histones following replication.
