Bacteria carry plasmids which is a double stranded DNA . It is how their extra chromosomal DNA is stored, they also have chromosomal DNA.
Plasmids are extra-chromosomal DNA in Bacterial cells that replicate independently in cell. Plasmids are ubiquitous- means significant number of bacteria have plasmid and can have more that one plasmids. But Plasmids do not occur in all bacterial isolates.

When the bacteriophage DNA becomes part of the bacterial chromosome?
During phage infection into bacteria, it penetrates phage DNA into bacterium,which will be integrated in to the bacterial genome (chromosome) to replicate and synthesize phage molecules.
What role plasmids have in a bacterial cell?
it is a circular genetic material (in bacteria) that can replicate separately from the DNA in the main chromosome.
When an original chromosome copies it self it is said to?
It is said to replicate
DNA molecules that can replicate independently of the main chromosomes of bacteria known as?
Plasmids
What happens to the chromosome numbers during meiois?
During meiosis, the chromosome number doubles because the cells replicate their DNA and split into two cells in meiosis I and in meiosis II, they replicate DNA and split once again, to form four cells.
When the bacteriophage DNA becomes part of the bacterial chromosome?
During phage infection into bacteria, it penetrates phage DNA into bacterium,which will be integrated in to the bacterial genome (chromosome) to replicate and synthesize phage molecules.
What is the extra ring called in bacteria?
The extra ring found in bacteria is called a plasmid. Plasmids are small, circular pieces of DNA that can replicate independently of the bacterial chromosome. They often contain additional genes that can provide advantages to the bacterial cell, such as antibiotic resistance or the ability to metabolize certain substances.
Does chromosome replication occur in mitosis and meiosis?
In normal eukaryotic cell cycle or in case of bacterial chrosome, DNA replication occur to replicate the whole chromosome.
HOW DOES A lysogenic infection help virus spread?
I don't know if this is what you are lookding for but here is what happens with a bacteriophage (a virus that infects bacteria) In a lysogenic infection the bactierophage DNA will insert itself into the bacterial chromosome and may replicate with the bacterium for many generations. (inactive) The bacteriohpage DNA can then exit the bacterial chromosome. If it does this then it can enter the LYTIC cycle.

When an original chromosome copies it self it is said to?
It is said to replicate
When the chromosome makes a copy of itself it is said to what?
duplicate or replicate
Phase of cell cycle when the organelles and chromosome replicate?
Interphase
Do mitochondria and choloroplast independently?
mitochondria= cellular respiration, chloroplast=photosynthesis
What does a replicate chromosome consist of?
A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
DNA molecules that can replicate independently of the main chromosomes of bacteria known as?
Plasmids
Who discovered plasmodesmata?
Plasmids are found within the nucleus of a cell, it is a small, circular piece of DNA found in bacteria and yeasts, which is able to replicate independently of the chromosomes. They are predominantly found in prokaryotes (in the cytosol of prokaryotes and some eukaryotes.--*Though plasmids are found in eukaryotes such as yeast, they are very rare in eukaryotes in general. Plasmids are much more prevalent in prokaryotes such as bacteria. Bacterial plasmids may be linear or circular and are basically pieces of DNA that carry non-essential genes and replicate independently of the bacterial chromosome. Since bacteria don't have nuclei, bacterial plasmids exist freely in the cytosol in a supercoiled manner. Examples of bacterial chromosomes include the F plasmid, which is essential to bacterial conjugation (horizontal gene transfer) and various resistance plasmids that confer resistance to toxins including antibiotics.
