Genome. Develop a data type to store the genome of an organism. Biologists often abstract away the genome to a sequence of nucleotides (A, C, G, or T). The data type should support the method addNucleotide(), nucleotideAt(), as well as isPotentialGene(). Develop three implementations. Use one instance variable of type String, implementing addCodon() with string concatenation. Each method call takes time proportional to the length of the current genome. Use an array of characters, doubling the length of the array each time it fills up. Use a boolean array, using two bits to encode each codon, and doubling the length of the array each time it fills up.
