Question

What are plasmids? How do they differ from the genomic DNA? Where are they located? what are the uses?

Answer 1

Plasmids are extrachromosomal, circular, double-stranded DNA found in Bacteria and yeast cable of replicating independently.

Genomic DNA of an organism consists of biological inheritable information which is needed to be passed from one generation to another. moreover, it consists of all the genes required for the survival of the organism.

Plasmid DNA is separate DNA from genomic DNA so it is known as extrachromosomal. It consists of additional genes that might be of use to the bearing organism like they can code for antibiotic resistance.

The plasmids are located inside the cell outside the genomic DNA.

The plasmids can be used as cloning vectors as an application of biotechnology.
