The cell nucleus through its several genes present on the chromosomes is responsible for regulating the proteins and influencing the traits of an organism.
No. Genetic codes are found on DNA or RNA. These code for the creation of proteins - and all products which determine the structure and function of an organism.
DNA
Proteins perform all of the required tasks, structure, and activity in living things. They are required for nearly all of the functions of an organism and without them, there would be no life.
Proteins are not hereditary material because of many reasons. Few of them are: No Uniformity in the structure: For a molecule to be carrier of heredity, It is important that its structure should remain universal. While, there is a lot of structural variation in the proteins, the structure of DNA is fairly same. The difference of the protein contents of the cells: Different cells in the same organism have different proteins and at different times in the same cells, the protein content varies. The DNA content of the all the cells in an organism are same irrespective of their location in body and time.

All proteins have structure.
The structure in cells where genes are found is called the nucleus. It is surrounded by a nuclear envelope and contains chromosomes, which are made of proteins and DNA. The DNA within the chromosomes carries the genetic information required for the functioning and development of the organism.
The proteins are made up of the DNA strands. The proteins will be determined by the DNA that is within the organism.
No. Proteins start out as a Primary structure, which is just the linear form and sequence of amino acids. The proteins then start forming alpha helices and/or Beta sheets depending on the properties of the amino acids. This is their Secondary structure The proteins then fold completely into tertiary structure. Here, we have a lot of hydrogen bonding and hydrophobic interactions within the protein between the helices and beta sheets. Many proteins are fully functional in their tertiary structure and don't have any reason for forming into a quaternary structure. In the quaternary structure, we usually see an interaction between 2 or more polypeptides or proteins. An example would be 2 proteins in their tertiary structure binding together to become a functional dimer. If 3 proteins were interacting it would form a trimer. Several proteins are functional only in a quaternary structure while several more proteins are just fine in their tertiary structure and therefore do not have a quaternary structure.
