Because they originated in Mesoamerica, chayote plants grow best in semi-tropical climates, although they have adapted to a number of growing conditions in warmer climates. The largest source of chayotes continues to be Central America, including Costa Rica, Mexico, the Dominican Republic, and Guatemala. Chayotes can: Prevent cardiovascular disease
Recombinant DNA is widely used in biotechnology, medicine and research. Today, recombinant proteins and other products that result from the use of rDNA technology are found in essentially every western pharmacy, doctor's or veterinarian's office, medical testing laboratory, and biological research laboratory.
2013 was an exciting time for genome engineering technology. A new system offered the first alternative to the current protein-based targeting (TALEN and Zinc Finger) methods used to specifically target a gene (or other DNA sequence). This new system uses a short RNA to guide a nuclease to the DNA target. This is CRISPR technology (Figure 1).
