Remember, RNA is made up of nucleotides like DNA.
RNA is different from DNA though:
-Has a ribose sugar instead of deoxyribose sugar
-Has Uracil (U) instead of Thyamine (T) for one of its nitrogen bases
-Is typically single stranded whereas DNA is a double stranded helix

Point mutations – mutations involving changes in one or a few nucleotides such as a substitution
