B2.2 - Inside bacteria
The electron microscope uses a beam of electrons to magnify x 2,000,000 Electron microscopes produce clear image; helping us discover more about cells. Bacterial cells do not have a nucleus Bacterial cells contain 2 types of DNA, Chromosomal DNA & Plasmid DNA Chromosomal DNA is a giant loop of DNA containing most genetic material. Plasmid DNA is a small loop that carries extra information
