20 Amino Acids
No, they code for amino acids (in sequence).
The sequence of nitrogenous bases (A, T, G and C) forms a code for the sequence of amino acids in a protein. The code is a triplet code. This means that three bases code for one amino acid. So, the order of the bases in a gene determines the order of the amino acids in a protein.
mRNA base pairs determine the sequence of amino acids in a protein during translation by matching with tRNA molecules that carry specific amino acids. The sequence of mRNA codons (three-base sequences) determines which amino acid is added to the growing protein chain. This process is guided by the genetic code, where each codon corresponds to a specific amino acid.

3 base pairs (3 letters) code for 1 aminoacid and this 3 base pair sequence is called a codon.

The instructions for arranging amino acids are stored in a cell's DNA, which contains the genetic code that specifies the sequence of amino acids in a protein. This genetic information is transcribed into messenger RNA (mRNA) and then translated by ribosomes to build the protein according to the instructions provided.

The process of converting mRNA into a sequence of amino acids is called translation. During translation, mRNA is read by ribosomes to produce a specific sequence of amino acids according to the genetic code. This sequence of amino acids then folds into a protein with a specific function.
Each amino acid is formed from three base pairs - if you remember, there are four bases in the DNA acid sequence: A, C, T and G. Therefore there is a maximum number of 64 different combinations of the amino acids together (43= 64). Therefore, for a protein with 100 amino acids, 100 DNA code triplets will be required :)
The DNA sequence TCAGCCACCTATGGA codes for the mRNA sequence UCAGCCACCUAUGGA, which translates to the amino acids Serine-Alanine-Threonine-Tryptophan. Therefore, this DNA sequence codes for 4 amino acids.
