Solutions For An Introduction to Genetic Analysis Chapter 8 Problem 22P

The transcription process would be initiated with the ribonucleic acid (RNA) polymerase enzyme fixing to the transcription initiation site (TATA box in eukaryotes). From this spot the transcription would be initiated and the entire gene including the exons (coding region) and introns (non-coding region) would be transcribed.

Transcription of the gene would be completed when the RNA polymerase enzyme runs over the poly-adenylation tail of the deoxyribonucleic acid (DNA). Before processing the end of the RNA transcript, it would be capped. Upon completion of transcription, the mRNA molecule would be processed through splicing.

During the process of splicing, specific regions at the end of the introns would act as recognition site for the splisosome to act upon and restrict the introns from the coding exons. The exons after processing would be ligated, that would contain the cap and the tail at the end and end of the transcript. The processed transcript would then move outside the nuclear membrane for translation to occur.
