RNA's Role in Balancing Protein Chirality Uncovered
Recent research published in Nature Communications reveals that RNA, a molecule thought to have played a crucial role in the early development of life, can favor the production of both left- and right-handed amino acids, challenging the notion that early life had a chemical predisposition for left-handed proteins. This finding deepens the mystery of why life predominantly uses left-handed amino acids, suggesting that life's homochirality might have emerged due to evolutionary pressures rather than chemical determinism.
