How many bases in the triplet code are required to synthesize a protein composed of 100 amino acids..?

A DNA molecule is made up by the pairing of the purines with the pyrimidines, the 4 nitrogenous bases. An mRNA molecule is transcribed from a DNA molecule in the nucleus. The proteins are synthesised from the mRNA on the ribosomes in the cytoplasm.The code for a single amino acid consists of three bases in the mRNA which is also called the codon.So if a protein consists of a length of 100 amino acids the gene for that protein would consist of 100 triplets or 300 bases.
