Archeabacteria type of reproduction is asexual process referred to as binary fission. This process is where repllication of its DNA happens which leads to the breaking of two new cells both with a replica of the DNA. Eubacteria reproduced also through binary fission. Binary fission or the division of the cell into two daugther cells happens next to the replication of the genetic material. binary fission is useful to bacteria as a way to propagate where the cell double its size then split into two new offsprings.
