WebMar 31, 2024 · A chromosome is a deoxyribonucleic acid (DNA) molecule with part or all of the genetic material (genome) of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle. WebChromosomes of bacteria have clear cytoplasmic shapes that are present in nucleoid. Proteins have structures similar to histone that coat the double helix DNA in the nucleoid. Many bacteria may have chromosomes that are circular in shape, large in size, and single, but it is not the same for all bacteria.
