If using a plasmid in order to express a large quantity of a particular protein (e.g. for protein purification) which of the following is NOT a requirement?The ability of the host bacterium to express GFP.A selectable marker that will facilitate retention of the plasmid.The presence of rep/ori genes that allows for replication of the plasmid in the bacterium of interest.A strong promoter that will drive transcription of the gene of interest and subsequent protein production.

Which of the following statements is true?Plasmids can only be transferred by cell division.Plasmids are found as part of the circular chromosome.Plasmids can replicate independently from chromosomal DNA.Plasmids always contain genes that are vital for survival of the organism.
