A plasmid which encodes genes for its own transfer.
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 extrachromosomal DNA capable of self replication.

Plasmid DNA is similar to chromosomal DNA in that it is double-stranded and carries genetic information in the form of genes. Both types of DNA can replicate and be passed on to new cells during cell division. However, plasmid DNA is typically smaller and found in the cytoplasm of the cell, separate from the chromosomal DNA located in the nucleus.
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.
Self-replicating DNA, such as a plasmid, is used in gene transfer techniques like bacterial transformation. The gene of interest is inserted into the plasmid, which can then replicate independently within a host cell, allowing for the transfer of the gene to another organism. This method is commonly used in genetic engineering to introduce new traits or gene functions into recipient organisms.
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.
