How is dna arranged in an animal cell

WebAnimal cells are eukaryotic because they have a defined nucleus and other membrane-bound organelles like mitochondria, Golgi apparatus, and endoplasmic reticulum. Other than the membrane-bound nucleus in the eukaryotic cell, these cells also indicate the presence of DNA inside the nucleus. Web15 feb. 2024 · Chromatin consists of complexes of small proteins known as histones and DNA. Histones help organize DNA into structures called nucleosomes by providing a base on which the DNA can be wrapped around. A nucleosome consists of a DNA sequence of about 150 base pairs that is wrapped around a set of eight histones called an octamer. 1
