FORMS OF REPRODUCTION IN PROKARYOTES

1. FORMS OF REPRODUCTION IN PROKARYOTES

2. BINARY FISSION The prokaryotic cell replicates its DNA, and the cell grows until it splits into two identical cells In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.

3. BINARY FISSION

4. CONJUGATION This involves the transfer of genetic material between two prokaryotic cells through a structure called a pilus the temporary union of two bacteria or  unicellularorganismsfor the exchange of genetic material . " immunity may be transferable by conjugation to other bacterial strains

6. TRANSFORMATION Prokaryotic cells can take up free DNA from their environment and incorporate it into their own genome

7. TRANSDUCTION This process involves the transfer of DNA from one bacterium to another via a virus ( bacteriophage) A  bacteriophage , often simply called a  phage , is a type of virus that specifically infects bacteria. The term “bacteriophage” comes from “bacteria” and the Greek word “ phagein ,” meaning "to devour
