Q. ‘Thiomargarita magnifica’, which was in news recently is:
Answer:
World largest bacterium
Notes:
- The bacterium — named Thiomargarita magnifica, or "magnificent sulfur pearl" is the world's largest bacterium discovered in a Caribbean mangrove swamp.
- The bacterium is roughly the shape and size of an eyelash. Most bacteria are microscopic, but this one is so big it can be seen with the naked eye.
- It not only contains DNA within a membrane, but also ribosomes—which create proteins—cohabitating with the genome.
- The cell has a structure that's unusual for bacteria. It has a large central compartment, or vacuole, that allows some cell functions to happen in that controlled environment instead of throughout the cell.
