R2 RNA element

Index R2 RNA element

The R2 RNA element is a non-long terminal repeat (non-LTR) retrotransposable element that inserts at a specific site in the 28S ribosomal RNA (rRNA) genes of most insect genomes. [1]

Biomolecular structure

Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function.

Cis-regulatory element

Cis-regulatory elements (CREs) are regions of non-coding DNA which regulate the transcription of neighboring genes.

Conserved sequence

In evolutionary biology, conserved sequences are similar or identical sequences in nucleic acids (DNA and RNA) or proteins across species (orthologous sequences) or within a genome (paralogous sequences).

Convergent evolution

Convergent evolution is the independent evolution of similar features in species of different lineages.

DNA

Deoxyribonucleic acid (DNA) is a thread-like chain of nucleotides carrying the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses.

Drosophila

Drosophila is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.

Hepatitis delta virus ribozyme

The hepatitis delta virus (HDV) ribozyme is a non-coding RNA found in the hepatitis delta virus that is necessary for viral replication and is the only known human virus that utilizes ribozyme activity to infect its host.

Messenger RNA

Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.

Primer (molecular biology)

A primer is a short strand of RNA or DNA (generally about 18-22 bases) that serves as a starting point for DNA synthesis.

Protein

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

Pseudoknot

A pseudoknot is a nucleic acid secondary structure containing at least two stem-loop structures in which half of one stem is intercalated between the two halves of another stem.

Retrotransposon

Retrotransposons (also called transposons via RNA intermediates) are genetic elements that can amplify themselves in a genome and are ubiquitous components of the DNA of many eukaryotic organisms.

Reverse transcriptase

A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription.

Ribosomal RNA

Ribosomal ribonucleic acid (rRNA) is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms.

Ribozyme

Ribozymes (ribonucleic acid enzymes) are RNA molecules that are capable of catalyzing specific biochemical reactions, similar to the action of protein enzymes.

Three prime untranslated region

In molecular genetics, the three prime untranslated region (3'-UTR) is the section of messenger RNA (mRNA) that immediately follows the translation termination codon.

Transcription (biology)

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.
