A Plasmid
Recombiant DNA
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.
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.
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.

Yes
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 =)

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.
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.

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.
