NEU 301 Lecture Notes - Lecture 44: Ftsz, Asexual Reproduction, Nucleoid
Document Summary
Asexual reproduction by division of one cell or body into two equal or nearly equal parts which occurs in prokaryotes (bacteria). Binary fission begins with the replication of the bacterial dna at a specific site - the origin of replication. The replication enzymes then move out in both directions from that site and make copies of each strand in the dna duplex. The enzymes continue until they meet at another specific site, the terminus of replication. Septation then begins, in which new membrane and cell wall material begin to grow and form a septum at approximately the midpoint of the cell. When the septum is complete, the cell pinches in two, and two daughter cells are formed, each containing a bacterial dna molecule. Region in which dna is located, it is distinct from the cytoplasm. In prokaryotes, dna exists as a single, circular double-stranded dna molecule.
