Microbiology

RNA World is a hypothesis that one of the first stages of Abiogenesis was dominated by RNAs.

• Miller–Urey experiment shows how amino acids and nucleobases can naturally form from inorganic components.

• RNAs could form at random from available nucleobases.

• RNAs that were more stable survived for longer.

• RNA can store and replicate genetic information.

• Ribozyme (RNA enzymes) can start or accelerate reactions that are critical for life.

• Ribosome (one of the most critical component of cells) is primarily RNA.

• Sugars (including ribose), amino acids, and nucleobases were detected in asteroids
