They are called chromosomes. More specifically, they are plasmids, and are only found in bacterias.

How many chromosomes does a bacterium have?
Bacteria do not have chromosomes. They have a small circular piece of DNA within the cell. The chromosome of a bacterium is the single molecule of circular DNA. It is also called as nucleoid.
What is a small circular segment of DNA found in many bacteria but separate from the bacterial chomosome?
The small circular segment of DNA is called plasmid.
What is inside the bacterium below is a small circular piece of DNA called?
Chromosomes unlike our cell they roam freely in the cytoplasm
Where and in what form is prokaryotic DNA found?
DNA is mostly circular, not linear or coiled (it is not like eukaryotic DNA). It is found floating freely anywhere in the cytoplasm but is most commonly found in a special region called nucleoid or false nucleus but is identified by dense region of the cytoplasm. Each piece of circular DNA is called a plasmid.
Do plants have circular DNA?
DO PLANTS HAVE CIRCULAR DNA

What do you call a small circular DNA molecule that is located in some prokaryotic cells like bacteria?
Plasmid (main circular DNA molecule) and transposons (smaller DNA loops).

Small circular molecules of extra DNA in bacteria are called what?
plasmids

What is a small circular DNA molecule found naturally in some bacteria?
plasmid
What are small circular segments of DNA often exchanged between bacteria?
Plasmid
What is the function of plasmids in DNA?
A plasmid is a small loop of DNA that contains genetic information to help bacteria perform functions such as making use of unusual food sources, resisting antibiotics meant to prohibit growth, or carrying the genes necessary to transfer DNA from one bacterium to another.
Assuming a circular piece of DNA was used as starting material how many restriction sites were there in lane three?
It takes one restriction enzyme to cut a linear piece of DNA (straight line) into two pieces. For a circular piece of DNA (plasmid), it would take two of these restriction enzymes - just think of how you would split a circle into two pieces; cutting one section will only straighten out the DNA, not split it (try cutting a rubber band for a visual).The answer to this question is completely dependent on the number of bands (representing different DNA fragment sizes) the lane produced. Since the first cut on a circular piece of DNA breaks the circle, then each consecutive cut will proceed as a linear band of DNA would.For example, if lane three produced four bands, then it took a total of three restriction enzymes (each enzyme reacting to one restriction site). Below is an example of the linear piece of DNA from lane three, with each "|" representing a restriction site. Notice how there are three restriction sites, but four fragments ("----") are produced.---- | ---- | ---- | ----As explained earlier, if a circular piece of DNA were cut to produce a linear piece like the one above, it would take one restriction site. From there, the enzymes proceed like the ones in the above example. Therefore, a circular piece of DNA that produced four bands would have used four restriction enzymes, whereas a linear piece of DNA that produced four bands would have used three restriction enzymes.
What is the difference between Plasmic DNA and Genomic DNA?
the genomic DNA large and is the one that forms chromosomes. however, the plasmedic DNA is a small circular vector of DNA (3 kb - 5 kb)
