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.

Best Answer: Bacteria, as mentioned in the previous answers, have no nucleus, so the DNA is located in the cytoplasm. However, the bacterial chromosome tends to be tethered to the plasma membrane. This area of the cytoplasm containing the chromosome is referred to as the nucleoid. just now. Report Abuse. bacteria's DNA floats freely through out its cytoplasm because bacteria are prokaryotic which means they are a type of cell that has no membrane bound organelles so no nucleus. this is unlike eukaryotic cells (plant and animals cells) in which the DNA is located inside the nucleus.
