Mutations:
A change in the RNA or DNA caused by one or more nucleotides changing locations.
This can happen when one nucleotide is inserted, deleted, or substituted for a different nucleotide
Un cambio en el ARN o el ADN causado por uno o más nucleótidos que cambian de ubicación.
Esto puede suceder cuando se inserta, elimina o sustituye un nucleótido por un nucleótido diferente.
