The Messenger of Life
RNA, or ribonucleic acid, is one of the essential molecules for life, serving as the messenger between DNA and proteins. Structurally, RNA consists of a single strand of nucleotides, made up of a sugar (ribose), a phosphate group, and four nitrogenous bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA’s versatile structure allows it to perform various functions. Messenger RNA (mRNA) carries instructions from DNA to ribosomes, while transfer RNA (tRNA) helps assemble amino acids into proteins. Other forms, like ribosomal RNA (rRNA), contribute to protein synthesis and gene regulation, ensuring vital cellular processes continue smoothly. [1]
The Web Of Life Beneath The Soil
In soil, RNA is essential for the microbial world. Microorganisms such as bacteria and fungi use RNA to process organic material, facilitating the breakdown of nutrients and enriching the soil. This microbial activity, powered by RNA, is crucial for maintaining soil health and supporting plant growth. Through this process, RNA acts as a messenger and builder, enabling the interconnected web of life beneath the soil. [2]
RNA World Hypothesis: The Seed of Life
The RNA World Hypothesis suggests that RNA was the first molecule capable of carrying instructions for life and constructing essential structures for growth. In the early stages of life on Earth, RNA served both as a blueprint for genetic information and as a builder, catalyzing vital reactions. This dual ability laid the groundwork for the evolution of DNA and proteins. Today RNA plays a key role in most cellular processes including the translation of the genetic information into proteins and regulation of genes expression, thus it is considered a key tool of biotechnology and bioengineering. [3]
RNA: The Memory of Soil Life
RNA plays a key role in soil’s “living memory,” enabling microorganisms to adapt and respond to environmental changes. In the context of odor modification, such as in the transformation of chicken litter into fertilizers, RNA helps regulate microbial activity that alters the chemical composition of soil. This process affects not only nutrient cycling but also the scents produced by microbial metabolism. RNA thus acts as a molecular record of microbial interactions, linking the past and present conditions of soil to its sensory impact on humans.
3D Models as a Reflection of RNA’s Memory
3D models of RNA are printed using biodegradable materials, symbolizing RNA’s role as a memory carrier. Just as RNA transmits information and enables transformation, these models, once buried, will dissolve into the soil, becoming part of its living system. This process also invites participants to reflect on their own memories, which will metaphorically return to the earth, just as RNA integrates back into biological systems.
