Protein structure prediction/protein . modelling. is the prediction of the three-dimensional structure of protein from its amino acid sequence. i.e., the prediction of its folding & its. In a day and age where people have busier lifestyles, where obesity is becoming a trend, and homes becoming smaller – manufacturers have created an empire surrounding quick and easy meals, snacks, and even drinks. More people prefer instant gratification, which led to wanting things done in an instant – instant messaging, instant coffee, instant noodles, and even instant meals! VBC-603. P.G.. 02.01.2021.
