DNA. Genes are made up of nucleic acids called DNA. Those genes are then transcribed into amino acid sequences called proteins. The dystrophin gene is much too large to spell out in a DNA sequence, and its protein is much too large to spell out in an amino acid sequence. Here is a link to some more information on the gene. http://www.ncbi.nlm.nih.gov/gene/1756.
Complex. many different forms of Dystrophin gene. Muscle Dystrophin, lymphocyte Dystrophin, fetal Dystrophin, Purkenji Dystrophin.... All of these genes are translated into proteins with some differences in amino acid combinations. A gene is never produced by amino acid combinations. Genes are made up of Nucleic Acids base combinations. Proteins are made from amino acids combinations.
3600+ amino acids. Dystrophin gene is the largest known gene found in nature measuring 2.4 million bases. The product of the transcription and translation of this gene is a very large protein of over 3600 amino acids. You can read more about this gene and the complete (abbreviated) amino acid sequence on the NIH website at http://www.ncbi.nlm.nih.gov/protein/NP_000100.2.
