Like bacteria, archaea are single-celled organisms. Genetically, however, there are significant differences between the two domains, especially regarding their cell envelopes and metabolic processes.

The origin of these microtubules has been unclear -- until now. In a newly published article in Cell , the ETH researchers discovered related structures in Asgard archaea and describe their structure.

"We still have a lot of unanswered questions about Asgard archaea, especially regarding their relation to eukaryotes and their unusual cell biology," says Pilhofer.

(A) Missing link between prokaryotes and complex cells identified A form of archaea with many of the proteins that make complex organisms possible.

Archaeal proteins that can aid in the fusion of cell membranes could offer insights into how complex life forms that undergo sexual reproduction may have evolved from simple cells, noted study ...

Scientists unlock secrets of how archaea, the third domain of life, makes energy Date: June 11, 2024 Source: Monash University Summary: An international scientific team has redefined our ...

The 12-year-long endeavor reveals Prometheoarchaeum as a tentacled cell, living in a symbiotic relationship with methane-producing microbes. Elusive Asgard Archaea Finally Cultured in Lab Elusive ...

Mitosis and meiosis are two kinds of cell division that are essential to most forms of life on earth. Here we investigate the key differences and similarities between the two processes.

The study of cell origins primarily involves the question of how cells became individual units, separate from the external environment and capable of producing energy to sustain themselves ...

The biggest is going to be how long a single cell can live. In Japan, researchers have estimated that between 1000 to 3000 years pass by in an instant for the slow metabolic rates we are dealing with.
