The genes for antibiotic resistance are found in
Open in App
Solution
The correct option is A Plasmid
Antibiotic resistance gene
Antibiotic resistance gene is a type of selectable marker to separate the transformed cells from the non-transformants after cloning. Alien gene is inserted at this site. The cells are then placed in the growth medium with the respective antibiotics that retards their growth, hence they can be separated from the non-transformants.
Examples include ampR in plasmid pBR322.
Source of antibiotic resistance gene
Antibiotic resistance genes are found in the plasmid that allows the organism to survive in a medium containing the respective antibiotics.
Plasmids
Plasmids are extranuclear, circular, double stranded DNA. They are usually used as vectors in genetic engineering.
Chromosome
Chromosomes are thread-like structures carrying long pieces of DNA, that are present in the cell and carry genetic information.
Nucleus
Nucleus is a double membrane enveloped structure which contains all the genetic information for controlling metabolism and transmission of characters.
Cell membrane
Cell membrane or plasma membrane is a selectively permeable membrane that separates the interior of the cell from the outside environment.
Final answer
(C) Plasmid
