WebArchaea and Bacteria generally have a single circular chromosome– a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. In contrast, many eukaryotes have multiple, linear chromosomes. Archaea and Bacteria reproduce through fission, a process where an individual cell reproduces its single chromosome and ... WebJul 30, 2024 · Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1).
