Structure of a eukaryotic chromosome
WebStructure of eukaryotic chromosome. A chromosome is an organized structure of DNA and protein that is found in the nucleus of the cell. It is a single piece of coiled DNA containing many genes, regulatory elements, and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. WebEukaryotic chromosomes consist of a DNA-protein complex that is organized in a compact manner which permits the large amount of DNA to be stored in the nucleus of the cell. The …
