Amino acids are the building blocks of proteins, not DNA, which makes up the genome.

amino acids?? 20 amino acids
There are nine essential amino acids. A protein is considered to be complete if it contains all nine of these amino acids.
There is a great degree of variability in the number of amino acids per protein. An answer to another question on WikiAnswers lists the shortest protein as 8 amino acids. According to the National Center for Biotechnology Information, the longest protein found in a sequenced genome is a "parallel beta-helix repeat-containing protein" in the organism Chlorobium chlorochromatii, this protein is 36,805 amino acids long.A protein may consist of as many as 5,000 amino acid molecules.
The monomers of proteins are amino acides. Amino acids make up proteins by combining into many different combinations. There are 20 amino acids that make up proteins.
The number of amino acids/protein differ largely and is characteristic for each protein separately. A protein is composed of amino acids, and the function of the protein depends of the type and order of the amino acids. Because amino acids can be arranged in many different combinations, it's possible for your body to make thousands of different kinds of protein from just the same 20 amino acids.The simplest protein of life, ribonuclease, contains 124 amino acids. The "average" protein, though, contains several thousand amino acids, but those several thousand comprised only about 20 different kinds of amino acids.
DNA contains no amino acids, it contains nucleic acids. Proteins can contain from 2 amino acids to tens of thousands.
It would take 19 peptide bonds to make a protein of 20 amino acids.

There are 20 amino acids used to make proteins by all living things. There are a few additional amino acids that some archaebacteria use to make proteins that are not used by other living things. There are many more synthetic amino acids that can be made, but while synthetic proteins can be made with them no living thing uses these additional amino acids.
We call the amino acids that the body can't make essential amino acids. We can get essential amino acids in our diet by consuming protein-rich foods such as meat, poultry, fish, eggs, dairy products, legumes, nuts, and seeds.
