A new study challenges origin of life theories, highlighting peptide amyloids' role in stabilizing genetic material.
Life on Earth originated around 3.7 billion years ago. Despite this being a crucial milestone in our planet’s history, the precise molecular mechanisms behind its emergence remain largely unknown.
has now proposed this co-evolutionary model where many molecules evolved together.Rather than a single molecule being the origin of life, as traditionally thought, the interdependence among various classes of molecules is crucial to the emergence of life. Think of RNA, or ribonucleic acid, as DNA’s cousin. While DNA has two strands and is considered the blueprint for life, RNA transmits genetic information and only has one strand.
Some amyloids exhibit catalytic capabilities, accelerating chemical reactions like complex biochemical processes.
