#Unit 3. Fundamental Processes

Errors in replication and damage to DNA have two consequences;
One is, of course, the introduction of permanent changes to the DNA (mutations), which can alter the coding sequence of a gene or its regulatory sequences.
The second consequence is that some chemical alterations to the DNA prevent its use as a template for replication and transcription
