Identifying The Last Universal Common Ancestor’s Protein Domains Resolves The Order In Which The Amino Acids Were Recruited Into The Genetic Code
We identified protein domains that emerged early in the history of life. Protein domains whose ancestors date back to a single homolog in the Last Universal Common Ancestor (LUCA) remain […]
