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.
Recombinant DNA technology (rDNA) is technology that is used to cut a known DNA sequence from one organism and introduce it into another organism thereby altering the genotype (hence the phenotype) of the recipient. The process of introducing the foreign gene into another organism (or vector) is also called cloning. gene library is a population of organisms, each of which carries a DNA molecule that was inserted into a cloning vector. Ideally, all of the cloned DNA molecules represent the entire genome of the organism.
