Compare this to how cars are built
observation ⇔ representation ⇔ modeling ⇔ animation ⇔ prediction in protein modeling for predictions: "Model Quality Assessment Programs (MQAPs) are also used to discriminate near-native conformations from non-native conformations." https://www.mdpi.com/1422-0067/20/9/2301
"The monomers can be grouped into segments like Lego pieces to construct functional protein-mimics. “Compare this to how cars are built,” said Xu. “There are different models, colors and shapes, but they all contain important parts such as an engine, wheels and energy source. For each part, there can be different options, such as gas or electric engines, but at the end of the day, it’s a car, not a train.” Xu and her team designed a library of polymers that are statistically similar in sequence, providing newfound flexibility in assembly."
