0 2bp insertion in middle of intron


What is the most likely effect of a 2bp insertion in the middle of the intron?
1. Normal transcription, altered translation.
2. Defective termination of transcription, normal translation.
3. Normal transcription, defective mRNA splicing.
4. Normal transcription, normal translation.
ANSWER:
Answer is A>D.
If the 2 bp insertion affects the translational regulatory elements , it will affect translation ; but if does not affect the translational regulatory elements , it will not affect translation. So ideally both ans a & d are right , but if to choose one - its better to go for A
