Detailed explanation-1: -Prokaryotes (bacteria and archaea) reproduce asexually through binary fission.
Detailed explanation-2: -Bacteria and archaea reproduce asexually by splitting one cell into two equal halves in a process called binary fission (Figure 1). Before a cell divides, it must first replicate the genome so that each daughter cell gets a copy of the DNA instruction manual.
Detailed explanation-3: -Archaea reproduce asexually by binary or multiple fission, fragmentation, or budding; meiosis does not occur, so if a species of archaea exists in more than one form, all have the same genetic material.
Detailed explanation-4: -Reproduction in prokaryotes is asexual and usually takes place by binary fission. The DNA of a prokaryote exists as as a single, circular chromosome. Prokaryotes do not undergo mitosis; rather the chromosome is replicated and the two resulting copies separate from one another, due to the growth of the cell.
Detailed explanation-5: -Only bacteria and archaea reproduce primarily by binary fission. Bacteria are sexually unable, although they are capable of transferring genetic information. Two bacteria come into contact through a pilus and exchange genetic material (a bacterial structure). This is known as conjugation.
