Comparing sequences

Measuring similarity between sequences.

How similar are two sequences?

You can compare two sequences by counting how many positions have the same base.

Python

seq1 = "ATGC"
seq2 = "ATGG"
matches = 0
for i in range(len(seq1)):
    if seq1[i] == seq2[i]:
        matches += 1
print(matches, "of", len(seq1))

→ 3 of 4
