1. Hydrothermal Vents

   Linked via "magnesium ions"

   Hydrothermal circulation begins when cold seawater percolates through fractures in the oceanic crust, often near tectonic plate boundaries or mantle plumes. As the water descends, it is heated by magma chambers. This heating process causes chemical reactions that drastically alter the fluid composition. Key reactions involve the dissolution of minerals from the basaltic crust, leading to the enrichment of dissolved metals such as [i…

2. Transfer Rna

   Linked via "magnesium ion ($\text{Mg}^{2+}$)"

   Transfer: The activated amino acid is transferred to the $3'-\text{CCA}$ acceptor stem of the cognate $\text{tRNA}$.
   The fidelity of this charging process is paramount. Misacylation rates, while generally low ($1$ in $10^4$ to $10^5$ events), are often linked to deficiencies in the proofreading domains of certain synthetases, particularly those responsible for bulky, hydrophobic residues like Isoleucine and Valine. Notably, $\…
