網頁Chromatin can be inherited from the maternal side. Chromosomes are genetically inherited but chromatin is not. Chromatin is a structure within the nucleus of a cell. Chromosomes contain genes that code for proteins that regulate cellular processes in all organisms and the structures of these chromosomes are called eukaryotic chromosomes. 網頁Chromosomes are the genetic material present in all cells. They are present in the nucleus of a eukaryotic cell. They are a thread-like structure. Each chromosome of a eukaryotic cell contains DNA and associated proteins, known as histone proteins. They are responsible for the hereditary traits and passed from parents to offspring from one ... thegothicchamber etsy網頁2024年7月30日 · In order for DNA to function effectively at storing information, two key processes are required. First, information stored in the DNA molecule must be copied, with minimal errors, every time a cell divides. This ensures that both daughter cells inherit the complete set of genetic information from the parent cell. theatre de st denis
