1. (a) Clearly identify (circle or outline) ALL of the individual biogenetic building blocks Nature used in the construction of each of the following THREE natural product structures. In addition, identify the natural product class, and sub-class where relevant, of each structure. Me- Me HO OH Me HO 1 Me Me (b) In the following reaction scheme, starting from structure 1 and using the reagents provided, draw the structures of the missing intermediate 2 and the product 3. NOTE: In the first step. 2 equivalents of the ketone (acetone) were used. OH OH HOT Me Me catalytic HCI OH 2 HO Mel AgO Me OH c) Given the following deoxyribonucleic acid sense strand sequence, CCCATGTTTTGA, provide the corresponding mRNA sequence, clearly indicating the position of the 5' and 3' ends, and then draw the structure of the peptide that could be biosynthesised based on the code embedded within the sequence of mRNA.
