To stop transmission, stopping the infectious agent can include;

  1. Stopping the agent from leaving the host through port of exit – e.g quarantine the patient
  2. Curtailing the modes of transmission – e.g killing disease vectors
  3. Protecting the ports of entry in the susceptible second potential host – e.g by improving immunity

When recombinant DNA is inserted into the genome of a host organism, what's created? A. A genetic marker B. A restriction enzyme
PIT_PIT [208]

The answer is C.

Transgenic means that one or more DNA sequences from another species has been introduced by artificial means. For example, animals usually are made transgenic by having a small sequence of DNA injected into a fertilized egg or developing  embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.

Most transgenic organisms are generated in the laboratory for research purposes. Others have been developed for commercial purposes  such as golden rice that has been modified to produce beta-carotene, the precursor to vitamin A.
