... Ribosomal RNAs (rRNAs) are components of ribosomes, which are large macromolecular assemblies that act as guides to coordinate the assembly of the amino acid chain of a protein. Ribosomes are composed of several types of rRNA and about 100 different proteins. As in the case of tRNA, the rRNAs are ge ...

Transposable element



A transposable element (TE or transposon) is a DNA sequence that can change its position within the genome, sometimes creating or reversing mutations and altering the cell's genome size. Transposition often results in duplication of the TE. Barbara McClintock's discovery of these jumping genes earned her a Nobel prize in 1983.TEs make up a large fraction of the C-value of eukaryotic cells. There are at least two classes of TEs: class I TEs generally function via reverse transcription, while class II TEs encode the protein transposase, which they require for insertion and excision, and some of these TEs also encode other proteins. It has been shown that TEs are important in genome function and evolution. In Oxytricha, which has a unique genetic system, they play a critical role in development. They are also very useful to researchers as a means to alter DNA inside a living organism.
