DNA and RNA Chemical Structure and Function | Baamboozle - Baamboozle

In the picture above, one of the nitrogenous bases has been knocked out by ultraviolet radiation. What is the consequence of this?

The original DNA sequence has been altered. You can call this a mutation. This will affect how mRNA is made and how a protein is made.
