Structure of a hammerhead ribozyme, a ribozyme that cuts RNA. Messenger RNA (mRNA) is the type of RNA that carries information from DNA to the ribosome, the sites of protein synthesis (translation) in the cell cytoplasm. The coding sequence of the mRNA determines the amino acid sequence in the protein that is produced. [27]
5' cap structure. A 5' cap (also termed an RNA cap, an RNA 7-methylguanosine cap, or an RNA m 7 G cap) is a modified guanine nucleotide that has been added to the "front" or 5' end of a eukaryotic messenger RNA shortly after the start of transcription. The 5' cap consists of a terminal 7-methylguanosine residue that is linked through a 5'-5 ...
Double-stranded RNA forms an A-type helical structure, unlike the common B-type conformation taken by double-stranded DNA molecules. The secondary structure of RNA consists of a single polynucleotide. Base pairing in RNA occurs when RNA folds between complementarity regions. Both single- and double-stranded regions are often found in RNA molecules.
Purified RNase V1 is a commonly used reagent in molecular biology experiments. In conjunction with other ribonucleases that cleave single-stranded RNA after specific nucleotides or sequences – such as RNase T1 and RNase I – it can be used to map internal interactions in large RNA molecules with complex secondary structure or to perform footprinting experiments on macromolecular complexes ...
Structure of CMCT used in RNA structure probing Mechanism of the reaction between uracil and carbodiimides [28] The carbodiimide moiety can also form covalent adducts at exposed nucleobases, which are uracil, and to a smaller extent guanine, upon nucleophilic attack by a deprotonated N. They react primarily with N3 of uracil and N1 of guanine ...
RNA is subdivided into many categories, including messenger RNA (), ribosomal RNA (), transfer RNA (), long non-coding RNA (), and several other small functional RNAs.. Whereas many proteins have quaternary structure, the majority of RNA molecules have only primary through tertiary structure and function as individual molecules rather than as multi-subunit structures

DNA and RNA also contain other (non-primary) bases that have been modified after the nucleic acid chain has been formed. In DNA, the most common modified base is 5-methylcytosine (m 5 C). In RNA, there are many modified bases, including those contained in the nucleosides pseudouridine (Ψ), dihydrouridine (D), inosine (I), and 7-methylguanosine ...
