Summary:
- All known living organisms, from bacteria to humans, copy their genetic information (DNA) into proteins, which are the building blocks of life. This process is called the "central dogma" of biology.
- However, a new study suggests that some ancient microbes called archaea may not follow this universal rule. Archaea are single-celled organisms that live in extreme environments like hot springs and deep-sea vents.
- The researchers found that archaea use a different mechanism to translate their genetic information into proteins, challenging the long-held belief that the central dogma applies to all life on Earth.
