Which of the following most used in genetic engineering?

Options

A. plastid
B. plasmid
C. mitochondria
D. ribosome

Answer

B

Explanation

Plastids are semiautonomous cell organelles . They take part in storage and synthesis of organic compounds. Mitochondria are called the power houses of the cell as they are the centres of Krebs cycle or respiration liberating the maximum amount of energy. Ribosomes are submicroscopic polypeptide manufacturing naked granular nucleoprotein cell organelles.
Plasmids are defined as autonomous elements, whose genomes exist in the cell as the extrachromosomal unit. These are the chromosomal element found in bacteria. Plasmids are used as cloning vectors, due to their increased yield potential.
