    • Primary structure
      • Linear sequence of amino acids in a polypeptide
      • This sequence is determined by genes and hereditary material, DNA. Correct sequence is important for proper functioning.
    • Secondary structure
      • Primary structure does not make a protein functional
      • Due to interactions with immediate neighbors, polypeptides tend to fold into pleats or wrap into coils forming the Secondary structure
        • Polypeptides folding into coils form alpha-helix structure
        • Polypeptides folding into plates form beta-plated structure. This structure is less stable than alpha-helix structure.
    • Tertiary structure
      • Bonds between neighboring amino acids results in further folded structure
      • Tertiary structure depends upon the primary structure
      • Creates active sites of enzymatic proteins
      • Some of the tertiary structures are spherical forming Globular proteins; while some others are like long fibers forming Fibrous proteins
    • Quaternary structure
      • Multiple chains of polypeptides held together by hydrogen bonds
      • Proteins with multiple chains of polypeptides only have this structure

    Vernalization ; It is the treatment of low temperature for reducing vegetative phase and hastening the reproductive phase. It was first discovered by Lysenko.
    Vernalisation refers specially to the promotion of flowering by a period of low temperature. For example - Subjecting the growing of a biennial plant to a cold treatment stimulates a subsequent photoperiodic flowering response.

    The low temperature treatment given to the seeds or seedlings to induce early flowering is known as vernalisation.

    A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids. Peptide bonds (also known as amide bonds) are the bonds that are found between two monomer units of amino acids in a polypeptide chain. They are created through condensation reactions in which a molecule of water (H2O) is removed.
