In genetic engineering, a DNA segment (gene) of interest, is transferred to the host cell through a vector. Consider the following four agents (A-D) in this regard and select the correct OPTION about which one or more of these can be used as a vector/vectors. A. A bacterium B. Plasmid C. Plasmodium D. Bacteriophage

Options

  1. AA, B and D only
  2. BA only
  3. CA and C only
  4. DB and D only

Correct answer

D. B and D only

Step-by-step solution

Plasmids are the extrachromosomal DNA found in bacterial cells. These are commonly used as vectors in genetic engineering programmes because these have the capacity of binding with eukaryotic DNA. Bacteriophage is a virus that is parasitic within a bacterium. These also, are the important tools in genetic engineering as cloning vectors.
