The following is a generalized diagram of a typical eukaryotic gene , What is the most likely effect of a 2bp insertion in the middle of the intron?: (A) Normal transcription, altered translation, (B) Defective termination of transcription, normal translation, (C) Normal transcription, defective mRNA splicing, (D) Normal transcription, normal translation
Answer is D. Introns are non-coding region of gene which are processed out of primary transcript. Hence, any change in intron will not effect transcription or translation.
