  2. Nucleic acid secondary structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_secondary...

    An RNA pseudoknot structure. For example, the RNA component of human telomerase. [7] 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.

  3. DNA and RNA codon tables - Wikipedia

    en.wikipedia.org/wiki/DNA_and_RNA_codon_tables

    [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. [2] [3] The mRNA sequence is determined by the sequence of genomic DNA. [4] In this context, the standard genetic code is referred to as ...

  4. Nucleic acid structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_structure

    Nucleic acid structure refers to the structure of nucleic acids such as DNA and RNA. Chemically speaking, DNA and RNA are very similar. Chemically speaking, DNA and RNA are very similar. Nucleic acid structure is often divided into four different levels: primary, secondary, tertiary, and quaternary.

  5. RNA - Wikipedia

    en.wikipedia.org/wiki/RNA

    In 1956 Alex Rich and David Davies hybridized two separate strands of RNA to form the first crystal of RNA whose structure could be determined by X-ray crystallography. [ 77 ] The sequence of the 77 nucleotides of a yeast tRNA was found by Robert W. Holley in 1965, [ 78 ] winning Holley the 1968 Nobel Prize in Medicine (shared with Har Gobind ...

  6. Messenger RNA - Wikipedia

    en.wikipedia.org/wiki/Messenger_RNA

    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 ...

  7. Nussinov algorithm - Wikipedia

    en.wikipedia.org/wiki/Nussinov_algorithm

    The Nussinov algorithm is a nucleic acid structure prediction algorithm used in computational biology to predict the folding of an RNA molecule that makes use of dynamic programming principles. [1] The algorithm was developed by Ruth Nussinov in the late 1970s.

  8. Ribonucleotide - Wikipedia

    en.wikipedia.org/wiki/Ribonucleotide

    Both types of pentoses in DNA and RNA are in their β-furanose (closed five-membered ring) form and they define the identity of a nucleic acid. DNA is defined by containing 2'-deoxy-ribose nucleic acid while RNA is defined by containing ribose nucleic acid. [1] In some occasions, DNA and RNA may contain some minor bases.

  9. List of RNAs - Wikipedia
