Detailed explanation-1: -Answer: Four amino acids can be coded for by this message.
Detailed explanation-2: -Because most of the 20 amino acids are coded for by more than one codon, the code is called degenerate. The genetic code, once thought to be identical in all forms of life, has been found to diverge slightly in certain organisms and in the mitochondria of some eukaryotes.
Detailed explanation-3: -Use the codon table to determine the sequence of amino acids that will be produced from a DNA or mRNA sequence. Use the codon table to determine which amino acid will be carried by a tRNA, given the anticodon sequence. Identify untranslated regions and include these regions in gene diagrams.
Detailed explanation-4: -The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA.
