A chromosome is an 'X' shaped gene which contains DNA, found inside living cells. Chromosomes are easily seen using a microscope and are normally invisible most of the time (tâ¦his period of time called 'interphase') but become visible when the cell starts to multiply.
Bacterial DNA â a circular chromosome plus plasmids. The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid.This sits in the cytoplasm of the bacterial cell.In addition to the chromosome, bacteria often contain plasmids â small circular DNA molecules. Bacteria can pick up new plasmids from other bacterial cells (during conjugation) or from the environment.his sits in the cytoplasm of the bacterial cell.

Viral DNA is the very simple DNA that runs the processes of viruses. Viruses can not live without feeding off of higher-level organisms, so there are not considered to be true â¦ life.If you know some about DNA, viruses have around 10,000 nucleotides. Bacterial DNA is much more complex, with millions of nucleotides.t becomes a part of the bacterial DNA and it can be replicated into the daughter cells. this cycle doesn't harm the bacterial cell but it can change into the lysis cycle and â¦ kill the host cell. 1 person found this useful.
