Module 8

Mutations as string changes

Modeling mutations with string operations.

Changes in the sequence

A mutation is a change in the DNA sequence. You can model a point mutation by replacing a character at a specific position.

Python
seq = "ATGC"
# Change position 1 from T to G
mutated = seq[:1] + "G" + seq[2:]
print(mutated)
AGGC
Your task

Model a mutation

  • Change position 1 of ATGC from T to G.
