[citation needed] It exhibits 7 aminoacyl tRNA synthetases (Table 2), the archetypes of enzymes previously thought only to be encoded by cellular organisms. While 4 of these enzymes were known to be present in Mimivirus and Mamavirus (for tyrosine, arginine, cysteine, and methionine), Megavirus exhibits three more (for tryptophan, asparagine ...
The Great Barrier Reef is the world's largest structure composed of living entities, stretching 2,000 km (1,200 mi) but contains many organisms of many types of species. When considering singular entities, the largest organisms are clonal colonies which can spread over large areas. Pando, a clonal colony of the quaking aspen tree, is widely ...
Pithovirus—the largest known virus; Parvovirus—smallest known viruses; Pelagibacter ubique—possesses one of the smallest bacterial genomes; Virophage—a virus that requires the host cell to be co-infected with a giant virus; The Giant Virus Finder is a software tool that identifies giant viruses in environmental Metagenomes.

The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size. Given the incomplete nature of scientific knowledge , it is possible that the smallest organism is undiscovered.
“And you know, we already have many fungi that cause a couple 100,000 deaths a year — we just ignore them, because we have this narrative that fungi are rare,” he added. The World Health ...
The discovery and subsequent characterization of giant viruses has triggered debate on their evolutionary origins. The two main hypotheses are that they evolved from small viruses by picking up DNA from host organisms; or that they evolved from very complicated organisms via genome reduction, losing various functions including self-reproduction ...
The world’s first confirmed coronavirus pandemic occurred in 2002, when SARS-CoV-1 was reported in China. It spread to more than two dozen countries in North and South America and Europe before ...
