Essentially, the plasmid can hold additional information, which codes for proteins that can sometimes be utilized by the host. Since polymerases work non-specifically, information can be transcribed from them and utilized by any host. DNA on plasmids can code for any protein. This codes for the Sex Pilus necessary for conjugation. It is very important that a plasmid have or associate with another plasmid with this ability in order for the plasmid to propagate.
Plasmids can also possess information for any protein sequence.
This means the plasmid can hold information necessary to deactivate an antibiotic and give its host antibiotic resistance. It may also be beneficial as gene sequences can be placed onto the plasmid and mass produced. For example Insulin can be placed on a plasmid and transferred to E. coli bacteria and mass produced. Part III Conjugation is the process at which genetic information is passed from one organism to another. Conjugation among bacteria involve the passing of a plasmid from a host bacteria to a recipient bacteria.
