Question

Suppose dna is a string variable that contains only 'a','c','g' or 't' characters. What Python code below can we use to find the frequency (max_freq) of the most frequent character in string dna?

dna_counts=
{'t':dna.count('t'),'c':dna.count('c'),'g':dna.count('g'),'a':dna.count('a')}
max_freq=sorted(dna_counts.keys())[0]

dna_counts=
{'t':dna.count('t'),'c':dna.count('c'),'g':dna.count('g'),'a':dna.count('a')}
max_freq=sorted(dna_counts.values())[-1]

dna_counts=
{'t':dna.count('t'),'c':dna.count('c'),'g':dna.count('g'),'a':dna.count('a')}
max_freq=sorted(dna_counts.keys())[-1]
