DNA is spliced into bacterial DNA in rings called plasmids.
Plasmids are small rings of genetic material. They are often referred to as "satellite DNA", and are found in many prokaryotes, bacteria included.
A small piece of bacterial DNA used for gene transfer is called vector DNA
A plasmid.

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 DNA synthesize in bacteria?

Mitocondria have the same structure as bacteria: outer lipid bilayer membrane, cytoplasm, large ring shaped DNA chromosome, small ring shaped DNA plasmids.
Bacteria's DNA is one chromosome that is literally a ring floating in the cytoplasm of the bacteria because they have no nucleus.
Bacteria generally have one (and only one) circular chromosome. However, they can also contain smaller rings of DNA called plasmids. These plasmids are generally not essential to cellular functions, but serve a variety of purposes. For example, they can serve as cloning vectors.

The small circular segment of DNA is called plasmid.
A plasmid is a circular ring of DNA that is separate from the main 'cluster' of DNA in a bacterium. They are not usually found in any other organisms apart from bacteria. They are used in genetic modification where and extra gene is inserted into the plasmid ring so the bacteria produces substances (such as insulin).
Bacteria are prokaryotes, that is, the DNA molecule is not enclosed in a membrane-bound nucleus as it is in the eukaryotes. In bacteria the DNA lies free in the cytosol in a region known as nucleoid. This is denser than the rest of the cytosol because of the presence of DNA and related protein molecules. Also the DNA in bacteria is not broken up in thread-like chromosomes but is a ring-like circular and continuous structure.
