Detailed explanation-1: -Statement IV is incorrect because, proteins are naturally synthesized starting from the N-terminus and ending at the C-terminus. Therefore conventionally, the first amino acid in a polypeptide chain is N-terminal amino acid and the last is the C-terminal amino acid.
Detailed explanation-2: -Plants store amino acids for longer periods in the form of specific storage proteins. These are deposited in seeds, in root and shoot tubers, in the wood and bark parenchyma of trees and in other vegetative organs. Storage proteins are protected against uncontrolled premature degradation by several mechanisms.
Detailed explanation-3: -Proteins help fight disease, control the rate of reaction and move substances into or out of cells. However, proteins do not store and transmit genetic information and thus the correct answer is A.
Detailed explanation-4: -Final answer: The given statement is true.
