Note

genetic code of each species of organisms enables species to survive and play its unique role on this earth Interrupting code may disrupt balance, but there can be benefits. We need to be careful and precautious when we delve into this risky business

Genetic Engineering

Definition

Genetic Engineering is a technique used to transfer genes from one organism to another. Individual Genes may be cut off from the cells of one organism and inserted into the cells of another organism of the same or different species. The transferred gene can express itself in the recipient organism #BiologyDefinitions


A Vector is required for the transfer of genes. Vector can be:

  • another DNA molecule
  • a bacterium or virus that is used to carry genes of one organism into another.

Small circular DNA called plasmids obtained from bacteria can be used to transfer genes

  • plasmid is example of vector

Gene of interest is any gene that we want to transfer from one organism to another. Key word TRANSGENIC
