CHEM 14C Study Guide - Final Guide: Ribose, Disulfide, Ion
Document Summary
In lecture we discussed the possibility that the first cells may have been formed in boiling mud puddles, which have been shown (in the lab) to produce fatty acids, carbohydrates, and primitive rna. When conditions are right (or so it is hypothesized) fatty acids assembled to form a micelle that just so happen to encapsulate rna. Questions 1 16 concern the molecules involved in this origin-of-life hypothesis. In a recent paper it was shown that melamine (m) and barbituric acid (ba) (both of which can be formed via the boiling mud scenario) structures resembling dna nucleobase pairs. into hydrogen-bonded self-assemble. 1. (4) dna (as we know it) requires nucleobase pairing via hydrogen bonding. Complete this statement by writing no more than six words in each space. A hydrogen bond donor requires a hydrogen atom 2. (3) in the m-ba base pair, m and ba are joined by three hydrogen bonds. Complete this drawing of the m-ba base pair.
