Answer: Cysteine residues are involved in disulfide bridges that helps to form tertiary structure in a protein
Explanation:
The tertiary structure of a protein will have a single polypeptide chain backbone with protein secondary structures. The interactions and bonds of the side chains within a protein determine its tertiary structure.
<u>The cysteine forms the disulfide bridges and they link the fragments within a polypeptide chain</u>. Sometimes those fragments are located very far from each other with respect to their primary structure. So, the tertiary structure is the three dimensional shape of a protein.
I will say mainly air pollution which destroys our ozone layer and let sun radiation come inside the earth...
Primary succession is ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).
