Describe how mature messenger ribonucleic acids (MRNAS) are post-transcriptionally processed in the nucleus before they are transported to the cytoplasm of a eukaryotic cell.

How would a null mutation in the guanylyl transferase gene affect overall mRNA stability in eukaryotic cells?

Using the transcription unit diagrammed below, in which exons are represented by blue boxes and introns are represented by the connecting lines.  You discover a single base deletion in region E of this DNA sequence. Regarding transcription, this mutation will likely: 1.) Result in an alteration to the mRNA sequence. 2.)Have no effect on transcription or the mRNA sequence 3.)Prevent transcription at the TATAA box 4.) Result in an increase or decrease in the amount of mRNA transcribed

Explain post transcriptional processing in eukaryotes

List three ways by which eukaryotes process mRNAafter transcription.

Give an account of post transcriptional modification of a eukaryotic Mrna?

Because DNA is found in the nucleus, transcription is a nuclear-localized process. Ribosomes responsible for protein synthesis are found in the cytoplasm. Why is hnRNP trafficking to the cytoplasm restricted to the nuclear pore complexes?
