Genetic codes are read in the sequence of 3. Insertion or deletion of a single base changes the reading frame of codon and is called frameshift mutation. However, insertion or deletion of three or its multiple bases insert or delete in one or multiple codon hence one or multiple amino acids and reading frame remains unaltered from that point onwards.
Under which of the following conditions will there be no change in the reading frame of the following mRNA? 5'AACAGCGGUGCUAUU 3'

Given below are two statements : Statement I : In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable. Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repairing mechanism. In the light of the above statements, choose the most appropriate answer from the options given below :
