The final 3-dimensional structure of a globular protein is defined by several types of structural units. Rank the following structural units in function of their complexity, starting from the bigger and more complex and ending with the smaller and less complex structural unit: Alpha helices, domains, peptide bonds, oligomers, reverse turns
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

Proteins are polypeptides consisting of unbranched polymers constructed from 22 standard α-amino acids. They have four levels of structural organization and undergo folding to attain functional specificity. These distinct structural levels are known as primary, secondary, tertiary and quarternary structures of a protein.
