The cells division is by binary fission. Prokaryotes have no cytoskeleton. Eukaryotes are the cells that contain a nucleus. Eukaryotes are found in fungi, plantae and several other places. WebDNA and in prokaryotes have developed three unique ways to transfer DNA: transduction, conjugation, and transformation. Transduction is defined as the process through which foreign DNA is introduced into a cell. Transduction does not require physical contact, instead DNA is transferred between bacteria by viruses called bacteriophages. theuber press manufacturing
