Alpha-helix and b-sheet, if occur together, are found in different structural layers.(a) True(b) FalseI had been asked this question in a job interview.I'd like to ask this question from Biopharmaceuticals in division Biopharmaceuticals of Drug Biotechnology

Answer»

The correct option is (a) True

For explanation: There some of the rules of secondary STRUCTURE and these are hydrophobic SIDE groups must be buried inside the FOLDS, therefore, layers must be created (b-a-b; a-a). Alpha-helix and b-sheet, if occur TOGETHER, are found in different structural layers. Adjacent polypeptide segments are stacked together. The b-sheet is the most STABLE.
