The fоllоwing is аn excerpt frоm а recent scientific publicаtion:“Because amino acid sequence determines protein structure and structure dictates biochemical function, proteins that share a similar amino acid sequence usually perform similar biochemical functions. Starting with the amino acid sequence of a protein, one can often predict which secondary structural elements… will be present in the protein. It is presently not possible, however, to deduce reliably the three-dimensional folded structure of a protein from its amino acid sequence unless its amino acid sequence is very similar to that of a protein whose three‑dimensional structure is already known. Additional information is required to understand the context in which the biochemical activity is used.” Which statement follows from the excerpt regarding prediction of protein function?
The fоllоwing is аn excerpt frоm а recent scientific publicаtion:“We will then use this understanding of protein structure at the atomic level to describe how the precise shape of each protein molecule determines its function in a cell. Proteins are therefore known as polypeptides. Each type of protein has a unique sequence… We start this paper by considering how the location of each amino acid… determines its three‑dimensional shape… precise shape of each protein molecule determines its function in a cell.” What essential principle is emphasized by this excerpt?
