Nucleic acid information from which of the following regions often leaves the nucleus: a. Introns b. Exons c.Promoters d.More than one choice listed e.Transposons Solution Answer : d. More than one choice listed Through exons and transposons. Exons are coding regions which is transcribed to mRNA which leaves nucleus for protein synthesis. Transposons are jumping genes which may get integrated into the region of exon Reason: Introns are non coding regions which are not transcribed to pass on the information. Promoters are regions in the DNA which initiate transcription but does not get transcribed..
