• Molecular scissors are basically restriction enzymes. These enzymes make one incision on each of the two strands of the DNA.
• Recombinant DNA Technology helps in the manufacturing of the novel enzymes which are needed in food processing.
• Cloning vector is a small piece of DNA which is taken from a virus, or a plasmid, or the cell of a higher organism.
• Since the DNA is hydrophilic, it cannot pass through the cell membrane.
