it is true that a eukaryotic cell. contains structures called organelles Eukaryotic cells contain organelles and histones, they have a well-defined nucleus, and are larger than prokaryotic cells. The function of a histone found in a eukaryotic cell focuses on cellular deoxyribonucleic acid (DNA) folding The histones are binding proteins that cause the supercoiling of DNA into chromosomes and do not affect cellular division, movement, or activities. An organelle that is responsible for th...
