Complete question:

Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons

  1. Amino acid sequences determine the three-dimensional structures of proteins.  
  2. Knowledge of the sequence of a protein can help to prevent mutations.
  3. The sequence of a protein reveals much about its evolutionary history.
  4. The sequence of a protein is necessary to determine its function.

Answer:  

Knowledge of the sequence of a protein can help to prevent mutations.

 Explanation:  

<em>Amino acids connect to each other by peptidic bonds </em>to form a <em>linear polymer</em>. The number of amino acids composing the chain and the order in which they are arranged determines the primary structure of the protein.

The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of <em>hydrogen bonds between the atoms that form the peptide bond.</em>

<u>Protein functions depend on their aminoacids sequences</u><u>.</u> <u>The primary structure of the proteins determines the three-dimensional one</u>. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

By knowing the sequence of amino acids, we can predict the function of the protein and we can classify them into different families. Integrants of these groups have at least 25% of their sequences identical to each other.  

Also, the knowledge of the sequence allows establishing evolutionary and genetic relationships between different species.

When a mutation occurs in the sequence -an alteration in the primary structure- the protein function is modified. BUT knowing the sequence of a protein CAN NOT help to prevent mutations.
