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 ... WebSince circular DNA lacks telomeres, it does not get shorter with each replication cycle. Circular DNA can also facilitate horizontal gene transfer such as Hfr mediated conjugation. Remember, conjugation is analogous to a "rolling-circle" type replication which is of course, only possible on circular pieces of DNA. Share.
