Which of the following best describes the formation of the tertiary structure of a protein? A B с D The sequence of the amino acids in the polypeptide chain has no effect on the tertiary structure of the protein. The interactions between the R groups in the polypeptide directly determine the tertiary structure of the protein. The dehydration reaction that covalently bonds the amino acids in the polypeptide di- rectly determines the tertiary structure of the protein. The number of amino acids in the polypeptide directly determines the tertiary structure of the protein.

Proteins

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.  

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
