Plasmids are additional to genomic DNA.What do we mean by genomic DNA?DNA that is part of a chromosome, therefore it is found in the genome of an organism.DNA that is not part of a chromosome, therefore it is found outside the genome of an organism.DNA that is made up of genes which carry information for different traits.DNA that is found floating free in the cytoplasmI DON'T KNOWSUBMIT ANSWER

Which of the following statements is true?Plasmids can replicate independently from chromosomal DNA.Plasmids are strands of linear DNA and carry genes useful for survival of the organism.Plasmids can only be transferred by cell division or fertilisation.Plasmids are found as part of the circular chromosome.

Which of the following describes plasmids?Synthesise proteins.Controls what enters and exits the cell.Small circles of DNA that are used to share useful genes between bacteria.Contains all the instructions the bacterium needs to function and develop.

What is a bacterial plasmid?Multiple choice question.A unique type of ribosomeAn internal structure where cellular respiration occursA small, circular piece of DNA separate from the bacterial chromosomeAn external appendage involved in motility

Plasmids used in cloning contain an antibiotic resistance gene.How does this help scientists?Choose 1 answer:Choose 1 answer:(Choice A)   Bacteria without the plasmid will be easier for scientists to identify.ABacteria without the plasmid will be easier for scientists to identify.(Choice B)   Only bacteria with the plasmid will grow on antibiotic containing nutrient plates. BOnly bacteria with the plasmid will grow on antibiotic containing nutrient plates.(Choice C)   It prevents the bacteria from infecting the scientists during the cloning process.CIt prevents the bacteria from infecting the scientists during the cloning process.(Choice D)   All of the prepared bacteria will be resistant to antibiotics.DAll of the prepared bacteria will be resistant to antibiotics.

Plasmids can be useful for many different elements of molecular microbiology but there are many considerations that dictate the features of a plasmid being used. 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.
