It is thought that in bacteria a plasmid can be used as a defense mechanism for fighting viruses. When the virus inserts itself to the bacteria, the bacteria can use its enzymes to disconnect the plasmid and carry the viral nucleic acid with it.

What is inside the bacterium below is a small circular piece of DNA called?
Chromosomes unlike our cell they roam freely in the cytoplasm
What is plasmid and what advantage might a bacterium gain by acquiring one?
Plasmids are circular pieces of dna, and a bacterium can gain its source
When plasmids are used to produce a desired protein what happens?
the desired gene is inserted into the plasmid and the plasmid is returned to the bacterium by transformation.
Do bacteria cell have single or multiple chromosomes of dna?
Prokaryotes contain a single circular chromosome. Some also carry smaller plasmids that are also round and contain few genes, transferred from bacterium to bacterium by conjugation.
Can a bacteraial plasmid replicate independently of the bacterial chromosome?
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.
What are plasmids?
A segment of DNA independent of the chromosomes and capable of replication, occurring in bacteria and yeast: used in recombinant DNA procedures to transfer genetic material from one cell to another.
What is the ring of DNA found in a bacterium in addition to the bacteriums main chromosomes?
That is known as a plasmid. The plasmid originally came from outside of the bacteria and was incorporated into the bacteria. Usually, these plasmids are beneficial to the bacteria that takes them in.
What causes protozoan plasmids?
Protozoa do not have plasmids in nature.
What is a promiscuous plasmids?
plasmids that have transfer systems that allow transfer of DNA to unrelated species are called promiscuous plasmids.
In many bacteria genes that confer resistance to antibiotics are carried on what dissimilation plasmids exons plasmids factors or transposons?
plasmids
What are the 2 types of DNA plasmids found in microorganisms?
Plasmids are autonomous DNA molecules of varying size which are localized within the cytoplasm of bacteria. There are two kinds:virulence plasmids = determines the virulence factors of the bacteriaresistance plasmids (R-plasmids) = determines the bacteria's resistance to anti-infective agents
Is prokaryote used in plasmids?
No, it's vise versa. Plasmids are used in and by the prokaryotes.
