Plasmid is extrachromosomal DNA capable of self replication.
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.
A self-transmissible plasmid is a type of plasmid that can transfer genetic material from one bacterium to another through a process called conjugation. This plasmid carries the necessary genes for forming a conjugative pilus and transferring the plasmid DNA. Self-transmissible plasmids play a significant role in horizontal gene transfer among bacteria.
plasmid is the type of the cloning vector. other cloning vectors includes cosmids, bacteriophage, phagemids, artifiical chromosomes. clonong vectors are the carriers of certain traits to be inserted in non coding regions of the DNA.
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.
R-plasmid
TOL plasmid
PUC18 is a plasmid, specifically a commonly used cloning vector in molecular biology research. It is small in size and contains a multiple cloning site for inserting DNA fragments, as well as antibiotic resistance genes for selection in bacteria.
You can determine if your bacteria contain a plasmid by performing a plasmid extraction followed by gel electrophoresis to visualize the presence of plasmid DNA. Other methods include PCR amplification of plasmid-specific sequences or using molecular biology techniques like restriction enzyme digestion to confirm the presence of a plasmid.
A plasmid which encodes genes for its own transfer.
Recombiant DNA
You can have a maximum of 8 plasmid slots.
The plasmid is found in prokaryotic cells.
