How do eubacteria reproduce?

Eubacteria reproduce through a relatively simple process known as binary fission, meaning "division in half." Most DNA can be contained on a single chromosome, which can reach great lengths if stretched out, and the bacteria duplicate the information and split into two. Archaebacteria use the same process.
