The proteins have 3 limbs one is brown one is purple and the other is green. Phenotypes are the are the contrasting color there for they make the organism work.
The statement that best describes the work of these researchers is "As a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done." I hope my answer has come to your help. God bless and have a nice day ahead!
