Answer:
It can lead to a mute, missense or nonsense mutation
Step-by-step explanation:
Single base substitutions are known as point mutations and there are two types:
1) Transversion: when a purine is substituted by a pyrimidine or viceversa
2)Transition: when a purine or pyrimidine is substituted by a base of the same nature, in simpler words purine - purine or pyrimidine-pyrimidine.
The three posible scenarios with this kind of mutations are:
1. Mute mutation: no effects overall because the substitutes base codifies for the same amino acid
2. Missense mutation: the base substituted codifies for a different amino acid
3. Nonsense mutation: the base substituted forms an stop codon
