(Bioinformatics:find genes) Biologists use a sequence of letters A , C , T , and G to model a genome. A gene is a substring of a genome that starts after a triplet ATG and ends before a triplet TAG , TAA , or TGA. Furthermore, the length of a gene string is a multiple of 3 and the gene does not contain any of the triplets ATG , TAG , TAA , and TGA. Write a program that prompts the user to enter a genome and displays all genes in the genome. If no gene is found in the input sequence, displays no gene. Here are the sample runs:
