The sequences found in the final mature mRNA has to be determined, and the structure of final mRNA has to be drawn. Concept Introduction: Transcription results in the synthesis of a primary transcript that undergoes some modification referred to as post-transcriptional modification. There are three kinds of post-transcriptional modifications that occur in eukaryotic primary transcripts, namely the addition of a 5′ cap structure and a 3′ poly (A) tail and the most significant is the RNA splicing. In most of the eukaryotic genes, there are certain sequences that do not encode any amino acid for the protein. Hence they are removed off in a process known as RNA splicing. The sequences that are not coding to any amino acids are termed as introns, and the important protein-coding regions are called exons.

Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…
