Document Summary

This was probably a consequence of accidental pollination. Commonly used these days for all kinds of baked goods. Put it into the dna of another organism. Instilling a set of instructions in the organism. Tells the organism what kinds of proteins to manufacture. We have been modifying food for several thousands of years. In 870 bc, assyrian relief art shows the artificial pollination of date palms. If you consider the grapefruit, this is just a hybrid of orange and pomelo. Triticale is a hybrid of wheat and rye. Genes are fragments of dna that code for specific proteins. You can take a piece of dna and snip it out. Protein molecule used in the making of cheese. Scientists, however, have discovered the particular gene that is used to form chymosin. This was the first product of genetic engineering that was introduced in our food supply. Much of the cheese that is produced today is based upon this technology.
