Answer:
1. Genes code for function of protein: False
2. The structure of protein is related to their function: True
3. There are different kind of proteins that serve different function: True
Explanation:
1. Not all genes code for proteins rather some of the genes encode RNA such as tRNA, rRNA,siRNA, etc. Further genes code for amino acids that makes protein and thus genes don't direct encode function of proteins.
2. The structure of a protein defines its function. If you disturb the structure of the protein, protein doesn't do its function. It is because of the reason that the catalytic (active) sites on proteins are disturbed and they don't allow binding. Thus, the metabolic reaction doesn't take place.
3. The proteins are formed through different arrangements and combinations of amino acids. We know that there are 20 amino acids generally and their different arrangements can make billions of proteins. Therefore, this argument is true that different kinds of proteins serve different functions.
