Plasmids are typically found in prokaryotic cells, such as bacteria. These small, circular DNA molecules can replicate independently of chromosomal DNA and often carry genes that provide advantageous traits, like antibiotic resistance. While plasmids can also be found in some eukaryotic cells, they are most commonly associated with bacterial cells.

What is an extrachromosomal piece of bacterial DNA that contains genes not essential for cell growth?
A Plasmid
What is the term for a plasmid that contains a foreign gene?
Recombiant DNA
What is the bacterial cell called when the f factor is in plasmid form?
When the F factor is in plasmid form within a bacterial cell, the cell is referred to as an F-positive or F+ cell. This means the cell carries the plasmid containing the F factor, which enables the cell to transfer genetic material during conjugation.
What is a helper plasmid?
A helper plasmid is one that allows for the beginning of replication and transfer of other plasmids from a donor to a recipient. Without a helper plasmid, transposons will not be expressed in the recipient.
Does an f strain donates a plasmid during conjugation?
No, in conjugation, the F strain serves as the donor of the plasmid (F factor) to the recipient cell. This transfer of genetic material allows the recipient cell to acquire the ability to carry out conjugation itself.

What is meant by ori region in a plasmid?
The ori region, or origin of replication, in a plasmid is a specific sequence of DNA where replication begins. It is necessary for the plasmid to replicate independently within a host cell. The ori region contains the necessary signals for the initiation of DNA replication.
What is the origin of replication in an expression plasmid?
The origin of replication in an expression plasmid is a specific DNA sequence that allows the plasmid to replicate, or make copies of itself, within a host cell. This sequence is essential for the plasmid to be maintained and passed on to daughter cells during cell division.
Why does bacteria that contains plasmid glow in uv light?
the plasmid contains a certain gene, which codes for the "Green Flourescent Protein." So you put the plasmid in the bacteria, the plasmid starts making that protein in the bacteria, and boom you've got glowing bacteria. works for bunnies and monkeys too, apparently =)
What must a bacterial cell have in order to transfer portions of its chromosome to another cell?
A bacterial cell must have a conjugative plasmid, which contains genes for the transfer of DNA, in order to transfer portions of its chromosome to another cell. Conjugative plasmids encode transfer functions that enable the formation of a conjugation bridge between donor and recipient cells, allowing the exchange of genetic material.
What is different of plant cell and an animal cell of plasmid?

What is a multicopy plasmid?
Every plasmid has a copy number that reflects the average number of copies of a certain plasmid inside a host cell(usually a bacterial cell). So a multicopy plasmid, exist in multiple copies in any given bacteria. It is believed that the higher the copy number is, the more efficient the plasmid is at replicating itself.
