Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions, either by performing the function itself (non-coding RNA) or by forming a template for the production of proteins (messenger RNA). RNA and deoxyribonucleic acid (DNA) are nucleic acids.
The standard RNA codon table organized in a wheel A codon table can be used to translate a genetic code into a sequence of amino acids . [ 1 ] [ 2 ] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes , it is messenger RNA (mRNA) that directs protein synthesis .
The labels Apt1, Apt2, Apt3, and Apt4 are in decreasing order of binding strength (i.e. Apt1 is the strongest aptamer). The DD, AD, DA, and AA letters mean that they have different combinations of unnatural base pairs. This causes their difference in binding strengths. The "-" columns have no protein, and the "+" columns do have protein.
Translation is accomplished by the ribosome, which links proteinogenic amino acids in an order specified by messenger RNA (mRNA), using transfer RNA (tRNA) molecules to carry amino acids and to read the mRNA three nucleotides at a time. The genetic code is highly similar among all organisms and can be expressed in a simple table with 64 entries.
The suffix -ome as used in molecular biology refers to a totality of some sort; it is an example of a "neo-suffix" formed by abstraction from various Greek terms in -ωμα, a sequence that does not form an identifiable suffix in Greek. Functional genomics aims at identifying the functions of as many genes as possible of a given organism. It ...
In molecular biology, trans-activating CRISPR RNA (tracrRNA) is a small trans-encoded RNA. It was first discovered by Emmanuelle Charpentier in her study of the human pathogen Streptococcus pyogenes , a type of bacteria that causes harm to humanity. [ 1 ]
The B2 RNA is a small noncoding RNA polymerase III transcript that represses mRNA transcription in response to heat shock in mouse cells. B2 RNA inhibits transcription by binding to core Pol II. Through this interaction, B2 RNA assembles into preinitiation complexes at the promoter and blocks RNA synthesis.
A transfer RNA to which a cognate amino acid is chemically bonded; i.e. the product of a transesterification reaction catalyzed by an aminoacyl-tRNA synthetase. Aminoacyl-tRNAs bind to the aminoacyl site of the ribosome during translation. amplicon Any DNA or RNA sequence or fragment that is the source and/or product of an amplification reaction.
