- Define the following terms: a. chromosome b. chromatinTrue or False: Mitosis results in daughter cells that are genetically the same as the parent cellTrue or False. De-acetylation of histone tails allows nucleosomes to pack together into tighter arrays, which usually reduces gene expression. Explain your answer in 1-2 sentences.
