In a prokaryotic cell their dna is in the
WebIn prokaryotes, three main types of polymerases are known: DNA pol I, DNA pol II, and DNA pol III. It is now known that DNA pol III is the enzyme required for DNA synthesis; DNA pol I and DNA pol II are primarily required for repair. How does the replication machinery know where to begin? WebMay 21, 2024 · Prokaryotic cells have ribosomes, which are molecules that make proteins. Their genetic material is in the nucleoid, which is the region where DNA lives. Additional rings of DNA called plasmids float around the cytoplasm. It is important to note that prokaryotes do not have a nuclear membrane.

DNA transfer between prokaryotic cells occurs in bacteria and archaea, although it has been mainly studied in bacteria. In bacteria, gene transfer occurs by three processes. These are (1) bacterial virus (bacteriophage)-mediated transduction, (2) plasmid-mediated conjugation, and (3) natural transformation. Transduction of bacterial genes by bacteriophage appears to reflect an occasional error during intracellular assembly of virus particles, rather than an adaptation of the h… WebThe genetic material of the prokaryotic DNA is in the form of circular DNA.
