What to Focus On

  • Biotechnology uses living organisms and biological processes for industrial applications.
  • It combines molecular genetics, microbiology, and biochemistry.
  • The term was first used by Carl Ericay in 1919.

  • Genetic engineering allows precise modification of DNA.
  • r-DNA technology enables gene transfer between unrelated organisms.
  • Gene cloning produces multiple copies of a desired gene.

  • Isolation of gene using restriction enzymes.
  • Vector (like plasmid) carries the gene into the host.
  • Host cells (e.g., E. coli) replicate the recombinant DNA.

Common Mistakes to Avoid

Recombinant DNA is the same as normal DNA found in organisms.

Gene cloning means making copies of entire organisms.

Genetic engineering and selective breeding are the same thing.
