Fig. 6.1 is a diagram showing the structure of part of a DNA molecule. [Figure 6.1] (b) Fig. 6.2 shows the RNA base sequence of a short length of primary transcript. Complete Fig. 6.2 by writing the DNA base sequence of the template strand used to form the primary transcript. [Figure 6.2] (c) In eukaryotic cells, the primary transcript is modified to form mRNA. Explain how the primary transcript is modified to form mRNA. (d) The mRNA strand is translated at the ribosome to form a polypeptide. Describe how the process of translation results in the formation of a polypeptide.
