Explanation:
The sequence of amino acids in a protein is determined by the DNA and the structure of protein thus formed is a linear sequence. These linear structures undergo structural changes due to the formation of bonds between the constituent molecules.
When bonds are formed by the interactions between the CO group of one chain and the -H group which forms the backbone is known as the secondary structures. Two types of arrangements arise of this that is the helical and pleated sheet.
