Bacteria normally contain their genome in a region called the nucleoid, which is not membrane-bound. The bacterial genome is typically organized as a single circular chromosome, although some bacteria may have additional small circular DNA molecules known as plasmids. This genomic structure allows for efficient replication and transcription within the bacterial cell.

How many nitrogen bases in a bacteria genome?
The number of nitrogen bases in a bacterial genome can vary depending on the species of bacteria. On average, a bacterial genome may contain around 1 to 10 million nitrogen bases. These nitrogen bases make up the genetic code of the bacteria and are responsible for encoding the information necessary for the bacteria to function and reproduce.
Which organelles inside bacteria make green fluorescent protein?
Organelles inside bacteria do not 'make' GFP. GFP can however be expressed in bacteria by adding the coding sequence for GFP to their genome. This can be done by using a plasmid virus containing the GFP gene sequence. When combined with the plasmid, a very small number of bacteria will take up the plasmid's genome into their own. These bacteria can be isolated by using the 'transform or die' mechanism. Bacteria that do not contain the plasmid are preferentially killed by adding an antibody to the agar. The normal bacteria will not be resistant to this, and will die, but the bacteria which have taken up the plasmid into their genome will also contain an antibody resistance gene. This allows them to live in the presence of the antibody. Since GFP was also added to these bacteria's genome, they will fluoresce.
Is it true mitochondria and chloroplasts originated in bacteria?
It is thought that chloroplasts and mitochondria were prokaryotic organisms and they were engulfed by a eukaryotic organism and instead of being digested by the cell a symbiotic relationship was formed. this is called endosymbiosis. the first scientist to pioneer this kind of thinking was Mereschkowsky back in 1905. Taking chloroplast as the example, most of the genes from the chloroplast genome have been intergrated into the nulcear genome. Those that are left are conserved in both the chloroplast genome and the cyanobacteria genome. (the cyanobacteria is the prokaryotic organisms that is thought to have been engulfed, thus creating the ancestor to the modern chloroplast). For example, the gene for bacterial cell division is also found in the chloroplast genome. Comparing both the modern chloroplast genome and the modern cyanobacteria genome it is possilbe to see just how many genes that where originally chloroplast based have jumped ship and gone to the nuclear genome. Both animals and plants contain mitochondria but only plants contain chloroplasts. This suggests that the endosymbiotic relationship between the eukaryotic cell and the mitcohondria happen before the animal and plant lines diverged.
Where is the genome located in a cell?
The genome is located within the nucleus of a cell. It is organized into structures called chromosomes, which contain the DNA that codes for an organism's traits.
Does the chloroplast contain bacteria?
Bacteria have prokariyotic cells.They do not have chloroplasts.

How is it possible to splice foreign DNA into a plasmid without altering the bacteria's ability to function normally?
A plasmid is an extra-chromosomal element. Strictly speaking, it is not a part of the bacterial mail genome. Plasmids, when first discovered in bacteria, were observed to contain genes that confer special features to the bacteria (like drug resistance). Also, a plasmid is capable of autonomous replication, which means it has its own origin of replication and does not have to wait for the bacterial genome to be replicated. When a foreign gene is inserted into a plasmid, the plasmid has to be transformed into the bacteria. Once transformed, the cDNA in the plasmid is able to replicate every time the plasmid replicated. This does not have any affect on the normal functioning of the bacteria. The organism is merely being used to make copes of the foreign gene and/or harvest an important protein product.

Do human lungs have bacteria in them?
There are no normally resident bacteria or viruses
Why is there salt in bacteria?
Bacteria doesn't contain salt.
Why don't cyanobacteria and bacteria reproduce by mitosis?
The reason bacteria do not reproduce by mitosis is because bacteria do not contain chromosomes. There are numerous types of bacteria.
Where is the genome located?
The genome is located inside the nucleus of a cell. It is made up of DNA molecules that contain the genetic information necessary for the development, growth, and functioning of an organism.
Does mitochondria have bacteria in it?
Mitochondria are evolved from bacteria.They do not contain bacteria.
