Stem cells do not create themselves

Summary: The energy-dependent cellular pathways have been detailed at all levels of examination from atoms to ecosystems in the context of physics, chemistry, and molecular epigenetics. The mere mention of RNA-mediated amino acid substitutions may cause theorists to panic because it eliminates their pseudoscientific nonsense in the context of the claim that proteins do not […]

Functionally interdependent editing and methylation

Editing and methylation at a single site by functionally interdependent activities …cytosine 32 in the anticodon loop of Trypanosoma brucei tRNAThr is methylated to 3-methylcytosine (m3C) as a pre-requisite for C-to-U deamination. Formation of m3C in vitro requires the presence of both the T. brucei m3C methyltransferase TRM140 and the deaminase ADAT2/3. Once formed, m3C […]
