7.1 DNA structure and replication: Post-Transcriptional Modification

Understanding that:
-Eukaryotic cells modify mRNA after transcription
-The regions of DNA that do not code for proteins should be limited to regulators of gene expression, introns, telomeres and genes for tRNAs
-Splicing of mRNA increases the number of different proteins an organism can produce
