I'm supposed to solve this in matlab, I dont know how to solve it using those functions I tried with different toolboxes but the nucleotides integers dont match the numbers on this problem. thanks for your help.Matlab question.

how to use char and find functions to solve it, a brief explanation as how to do it, it's all I need. thanks.

how can I create a random vector of 25 elements with those letters simulating a dna sequence in matlab. observe that the values have to match those of the base pairs.

Assign to the letter A the number 1, to the letter T the number 2, to the letter C the number 3 and to the letter G the number 4. Create a row vector with 25 random outcomes of these four letters and call it gene. (Hint: find(), char()
