Topics in Biotechnology

1

Introduction to Biotechnology

  • Biotechnology uses biological processes, organisms, or systems to develop products for human use.
  • It includes applications in agriculture, medicine, and industry.
  • The term 'biotechnology' was first used by Carl Ericay in 1919.
2

Genetic Engineering and r-DNA Technology

  • Genetic engineering involves artificially manipulating DNA to change an organism’s characteristics.
  • Traditional breeding cannot transfer genes between unrelated species; genetic engineering can.
  • Recombinant DNA (r-DNA) technology allows insertion of foreign genes into host organisms.
3

Steps in Recombinant DNA Technology

  • Isolation of the desired gene using restriction enzymes.
  • Insertion of the gene into a vector (like a plasmid).
  • Introduction of the recombinant vector into a host cell (like E. coli).
4

Applications of Biotechnology

  • Pest-resistant and drought-tolerant crops are developed using r-DNA technology.
  • Crops with higher nutritional value (e.g., Golden Rice) are produced.
  • Nif genes for nitrogen fixation can be introduced into plants.
