That RNA can act as a template and also now exhibits catalytic activity fuelled hypotheses for the evolution of an “RNA world”. 34 In this scenario RNA is the primary polymer of life that replicates itself. DNA and proteins were later refinements. So the first genes were short strands of RNA that reproduced themselves, perhaps on clay surfaces. This conjecture is strengthened by the fact that in cells today there are segments of some eukaryotic pre-rRNAs which can cleave themselves off and join the two cut ends together to reform the mature rRNA. In 1982 Thomas Cech and his colleagues at the University of Colorado discovered this can take place in the absence of protein in the ciliated protozoan Tetrahymena thermophila . 35 Just as remarkable are the small nuclear RNAs (snRNAs), which complex with protein to form small nuclear ribonucleoproteins (snRNPs; pronounced “snurps”). Particles called spliceosomes convert pre-mRNA to mRNA. 36 Other ribozymes include the hammerhead variety and RNAse P, which generates the 5 ' ends of tRNAs. The former are found in certain plant viruses. Origin-of-life theories see prebiotic significance in these ‘vestigial’ post-translational mechanisms.

The treatment of liver pain rests on the ability of individuals to refrain from certain habits such as drug addiction and alcoholism which is the root cause of most health problems. Treatments available medically are antiviral agents, 3TC, Adefovir, Flagyl, Interferon alpha II b. Along with these, sufficient electrolyte repletion and hydration is necessary for facilitating the treatment of liver pain. Moreover maintaining ones personal hygiene along with good sanitary measures are common follow up measures for the treatment of any disease. Patients are referred to the hospital only if they are unable to eat food and there is a need to compensate the loss by resting on saline treatment.

Fatty acid biosynthesis (and most biosynthetic reactions) requires NADPH to supply the reducing equivalents. Oxaloacetate is used to generate NADPH for biosynthesis in a two‐step sequence. The first step is the malate dehydrogenase reaction found in the TCA cycle. This reaction results in the formation of NAD from NADH (the NADH primarily comes from glycolysis). The malate formed is a substrate for the malic enzyme reaction, which makes pyruvate, CO 2 , and NADPH. Pyruvate is transported into the mitochondria where pyruvate carboxylase uses ATP energy to regenerate oxaloacetate.
