What is ribosomal RNA?
The ribosome is the main machine in the cell. It is the molecular mechanism that takes the information stored in the gene and translates it into information in protein sequence. It’s just like translating a tape written in one language into a tape written in another. And ribosomal RNA is the core of the ribosome. The ribosome comprises both RNA and protein and in effect the ribosome comprises also two subunits-one is about double the size of the other-each of which contains a core of RNA surrounded by special proteins. Define archaea? The archaea are what has been called at various times the third form of life. What is meant by that is the following and it has to be set in a historical context. For years and years, people thought that at base there were two types of organisms on this planet. The so-called eukaryotes are represented by animals, plants, and everything you can see with the naked eye that is living, including certain microscopic things, such as the familiar paramecium. And
