writ code using python. Code Challenge: Recall that a DNA sequence is a string over the alphabet {A,C,G,T}. The GC-Content of a DNA sequence is the proportion of characters of the sequence that are either G or C. For example, the GC-Content of the sequence ACGTA is 2/5 = 0.4.
Write a function (either iterative or recursive) gc_content() that takes in one string parameter seq and returns the GC-Content of seq.
Sample Input:
ACGCGCGCCT
Sample Output:
0.8
