Tertiary Structure
Tertiary structure refers to the three-dimensional structure of the entire polypeptide chain.
Full article >>>

Tertiary structure is considered to be largely determined by the protein's primary sequence, or the sequence of amino acids it is composed of.

Tertiary structure
In biochemistry, the tertiary structure of a protein is its overall shape.

Often refers to breaking hydrogen bonds between base pairs in double-stranded nucleic acid molecules to produce in single-stranded polynucleotides or altering the secondary and tertiary structure of a protein, destroying its activity.

These helices, strands, turns, and coils interact chemically with each other to form the unique three-dimensional shape of the protein, called the tertiary structure.

In DNA it refers to the separation of the two component strands caused by the breaking of the hydrogen bonds. In proteins, it refers to disruptions in the secondary and tertiary structure of the protein, destroying its activity.
