I think that an altered plasmid is one that has just undergone transformation, so it has the two combined vectors inside of it.
A plasmid is considered recombinant when it contains DNA sequences from two different sources that have been artificially combined, often through genetic engineering techniques like restriction enzyme digestion and ligation. This results in a plasmid with modified or additional genetic material compared to its original form.
If a plasmid is cut at more than one site by restriction enzymes, it would result in multiple DNA fragments. These fragments can be ligated back together in different combinations, resulting in plasmids with different sizes or configurations. This can lead to the creation of recombinant plasmids with altered properties compared to the original 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.
Recombiant DNA
In the production of a recombinant plasmid, the DNA of interest (insert) and the plasmid vector are both cut with restriction enzymes to create compatible ends. These cut fragments are then ligated together using DNA ligase to produce the recombinant plasmid.

R-plasmid
TOL plasmid
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.
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.
You can have a maximum of 8 plasmid slots.
Recombiant DNA
The plasmid is found in prokaryotic cells.
In the production of a recombinant plasmid, the DNA of interest (insert) and the plasmid vector are both cut with restriction enzymes to create compatible ends. These cut fragments are then ligated together using DNA ligase to produce the recombinant plasmid.
