    Eukaryotic genes differ than prokaryotic genes. Please explain, in depth, the post-transcriptional modification that a eukaryotic mRNA goes through before it leaves the nucleus and how this differs from the transcriptional events in a prokaryotic system.

    Features of mRNA transcription in Eukaryotes

    In eukaryotic genomes, mRNA is initially synthesized as a primary RNA transcript. Because eukaryotic genes are composed of coding (exons) and non-coding (introns), post-transcriptional splicing is required to remove the intron sequences and join the remaining exons into a functional mRNA.

    One obstacle for cells is the short half-life of mRNA. In order to increase the half-life, and therefore stability, of ...

    Solution Summary

    In a nutshell this solution talks about the major differences between prokaryotic and eukaryotic mRNA. Everything from caps to tails and cistrons to introns. The solution wraps up with a small summary table for quick reference.
