|
|
All proteins have the same function, to encode genes.
|
|
|
Proteins that have different structures will have different functions.
|
|
|
Protein structure does not affect the protein at all.
|
|
|
What is a protein?
|
Detailed explanation-1: -No two proteins with different amino acid sequences (primary structure) have identical overall structure. The unique amino acid sequence of a protein is reflected in its unique folded structure. This structure, in turn, determines the protein’s function.
Detailed explanation-2: -The structure of protein sets the foundation for its interaction with other molecules in the body and, therefore, determines its function.
Detailed explanation-3: -The sequence of amino acids determines each protein’s unique 3-dimensional structure and its specific function. Amino acids are coded by combinations of three DNA building blocks (nucleotides), determined by the sequence of genes.
Detailed explanation-4: -Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
