Answer:
The right answer is A)The primary structure of a protein is the order of amino acids in a polypeptide, as coded for in the DNA of a gene.
Explanation:
Proteins are aminoacids´s polymers. There are 20 different aminoacids that differs only in their R groups. There are four kind of protein structures:
1) Primary structure: it refers to tha secuence of aminoacids in the protein and is defined by DNA.
2) Secondary structure: it describes the situation in which we can identify repeated segments along the polypeptid chain. There are two secondary structures: alpha helix and beta pleated. This two conformation are held together by interactions between peptidic groups. R groups can interact only if they are small.
3) Tertiary structure: is the three-dimentional conformation of the polypeptid and it is stabilized by hydrogen bonds, electrostatic interactions, hydrophobic interactions and disulphide bonds. Stabilizing bonds can be between peptidic groups (peptide bond).
4)Quaternary structure: it applies for that proteins conformed by different subunits. It describes the conformation and interaction between these subunits in the polypeptid.
