R-plasmids contain genes for antibiotic resistance and they can be transferred among bacteria. It is common for gut bacteria of humans and other animals to spread antibiotic resistance this way. It is a problem for humans because many bacteria have become resistant to multiple antibiotics.

Why is a plasmid a good way of getting recombinant DNA into a bacteria?

plasmids are very useful in recombinant DNA technology because ; 1. it has own origin of replication. has some selective markers like ; Amp^r, ter^r etc. 3. it has unique recognition sequence . has specific restriction sites . 5. it is small in size because in RDT foreign DNA is inserted , if the vector is large sized then after insertion it will creat problem . but due to the small size plasmids donot creat any problem.
