Deoxyribonucleic acid, or dna, is comprised of four bases: (g)uanine, (c)ytosine, (a)denine and (t)hymine. ribonucleic acid, or rna, is different than dna in that it contains no thymine; thymine is replaced with something called (u)racil. for this assignment, you will create an array of 255 characters. you must start by filling the array with random characters of g, c, a and t. you must then print out the array. next, replace all the instances of thymine with uracil. finally, you must print out the array again. in your solution, you must write at least one function that contributes to the solution. you must use the length attribute of the array in your answer.
