Introduction and Review
... Introns are removed, and the exons are spliced together, by ribonucleoprotein particles called spliceosomes. mRNA contains a “leader sequence” at its 5’ end, before the coding region. The coding region begins with a translational initiation codon (AUG). A methylated guanosine cap is added to the 5’ ...

Regulation of Gene Expression
... Alternative RNA splicing – where different mRNA molecules are produced from the same primary transcript, depending on which RNA segments are treated as exons and which as introns. Regulatory proteins specific to a cell type control intronexon choices by binding to regulatory sequences within the pri ...

Heterodimeric transcription factors increase regulatory diversity and gene-control options (a) Many transcription factors (e.g. b-Zip and helix-loop-helix proteins) can form both homodimers or heterodimers with other members of the same class.
