DNA is a single strand; its location is in the nucleoid region (center of cell) which contains all instructions for making more bacterial cells.
You have chromosomes in your cells that allow you pass on genetic information, and so do bacteria. Bacterial have single, circular chromosomes, along with extra pieces of DNA called plasmids. The chromosomes and plasmids store a bacteria’s entire DNA.
DNA. Those three little letters have a lot of meaning. You've probably heard DNA called 'the building blocks of life' in a science fiction movie. DNA takes the shape of a double helix, often described as looking like a twisted rope ladder. The DNA is wrapped up around protein to make a material called chromatin. One long piece of chromatin is called a chromosome. You can remember this by thinking of a scarf. The material is the yarn (chromatin), and one long piece of the yarn (chromosome) is a scarf.
