The part of sequence of RNA coding for a protein and it's mutated sequence is given below.

Normal sequence : AGC- GCC- GAA- AGA- AAG- AUG- ACG
Mutated sequence : AGC- GCC- GAA- UGA- AAG- AUG- ACG

Type of mutation shown above is
AGA is mutated to UGA (Adenine is replaced by Uracil) Coding region is converted to Stop Codon. So it is a Nonsense point mutation.
Missense mutation
Nonsense mutation
Silent mutation
Frame shift mutation
