- Discutir las implicaciones potenciales de las mutaciones a nivel celular, organizativo y evolutivo.
- Describir la estructura del ADN y el proceso de replicación del ADN.
El ADN es un ácido nucleico, que es una de las cuatro macromoléculas biológicas que comenzaste a aprender en BI211. Recordemos que los ácidos nucleicos están constituidos por monómeros llamados nucleótidos unidos entre sí por fuertes enlaces covalentes.
Todos los seres vivos almacenan información genética utilizando ácidos nucleicos: ya sea ADN o una molécula relacionada llamada ARN. Diferentes organismos tienen diferentes formas de empaquetar y almacenar el ADN dentro de sus células.
