The first level of organization of a protein is created by a linear sequence of a) amino acids. b) nucleic acids. c) nucleic bases. d) polymeric peptides.

Answer : The first level of organization of a protein is created by linear sequence of  (A)amino acids.There  are four levels of protein based on their structure . The primary structure is made of amino acid sequence. the structure is held by peptide bond that are made during the process of protein biosynthesis. The primary structure of protein is linear sequence .

For example, insulin is composed of 51 amino acids in 2 chains. One chain has 31 amino acids, and the other has 20 amino acids.
