What makes RNA mutate at a faster rate than DNA?

Step-by-step solution

Both DNA and RNA are able to mutate. In fact, RNA being unstable, mutates at a faster rate. Consequently, viruses having RNA genome and having shorter life span mutate and evolve faster. RNA can directly code for the synthesis of proteins, hence can easily express the characters. DNA, however, is dependent on RNA for synthesis of proteins. The protein synthesizing machinery has evolved around RNA. The above discussion indicates that both RNA and DNA can function as genetic material, but DNA being more stable is pre
