What are Cry proteins? Name an organism that produce it. How hasman exploited this protein to his benefit

Cry proteins are a family of toxins produced by the bacterium Bacillus thuringiensis (Bt). These proteins are toxic to many species of insects, but are harmless to humans and most other animals.

Bacillus thuringiensis is the organism that produces Cry proteins. This bacterium is commonly found in soil and can survive in a variety of environments.

Humans have exploited Cry proteins in several ways, most notably in agriculture. Bt toxins have been used as a pesticide to control insect pests for many years. More recently, genes encoding Cry proteins have been introduced into crops to create genetically modified (GM) plants that are resistant to certain pests. This has allowed farmers to reduce the use of chemical pesticides, which can have harmful environmental effects.

In addition, Cry proteins have been used in research to study the mechanisms of insect resistance to Bt toxins, which can help in the development of new strategies for pest control.
