Genes, Transcription and Translation - Quick revision sheet A gene is a section of DNA that codes for a particular p The order of the b_____ in a gene determines the order of the a __ in the protein. has a different Each gene contains a different sequence of b____. Therefore each p___ combination of amino acids. The amino acids in the protein f___ up to give each protein a different, specific function. E.g. enzymes (which are proteins) have a specific shape. A sequence of three bases in the DNA is called c____ protein. DNA contains f___ different bases (a_ they can combine to make 64 different codons. There are only 20 amino acids, so there is more than one codon coding for each amino acid. and codes for one a .,8_ t ___a____ in the and c_ _) so Some regions of DNA are n__- c___ .. They don't code for amino acids, but they are still involved in protein synthesis.
