  2. RNA origami - Wikipedia

    en.wikipedia.org/wiki/RNA_Origami

    RNA origami mechanism. RNA origami is the nanoscale folding of RNA, enabling the RNA to create particular shapes to organize these molecules. [1] It is a new method that was developed by researchers from Aarhus University and California Institute of Technology. [2] RNA origami is synthesized by enzymes that fold RNA into particular shapes.

  3. Nucleic acid secondary structure - Wikipedia

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

    This may be because 10% of genes in zebrafish have alternating TG and AC base pairs at the 3' splice site (3'ss) and 5' splice site (5'ss) respectively on each intron, which alters the secondary structure of the RNA. This suggests that secondary structure of RNA can influence splicing, potentially without the use of proteins like U2AF2 that ...

  4. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    Nucleic acid types differ in the structure of the sugar in their nucleotides–DNA contains 2'-deoxyribose while RNA contains ribose (where the only difference is the presence of a hydroxyl group). Also, the nucleobases found in the two nucleic acid types are different: adenine , cytosine , and guanine are found in both RNA and DNA, while ...

  5. Nucleic acid sequence - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_sequence

    Frequently the primary structure encodes motifs that are of functional importance. Some examples of sequence motifs are: the C/D [12] and H/ACA boxes [13] of snoRNAs, Sm binding site found in spliceosomal RNAs such as U1, U2, U4, U5, U6, U12 and U3, the Shine-Dalgarno sequence, [14] the Kozak consensus sequence [15] and the RNA polymerase III ...

  6. Nucleic acid tertiary structure - Wikipedia

    en.wikipedia.org/.../Nucleic_acid_tertiary_structure

    Walter and Turner found that, on average, prediction of RNA structure improved from 67% to 74% accuracy when coaxial stacking contributions were included. [23] Most well-studied RNA tertiary structures contain examples of coaxial stacking. Some prominent examples are tRNA-Phe, group I introns, group II introns, and ribosomal RNAs.

  7. 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 ...

  8. Nucleic acid structure prediction - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_structure...

    The simplest way to find the lowest free energy structure would be to generate all possible structures and calculate the free energy for it, but the number of possible structures for a sequence increases exponentially with the length of RNA: number of secondary structures = (1,8) N, N- number of nucleotides.

  9. Ribonucleotide - Wikipedia

    en.wikipedia.org/wiki/Ribonucleotide

    The RNA chain is synthesized from the 5' end to the 3' end as the 3'-hydroxyl group of the last ribonucleotide in the chain acts as a nucleophile and launches a hydrophilic attack on the 5'-triphosphate of the incoming ribonucleotide, releasing pyrophosphate as a by-[6] product. Due to the physical properties of the nucleotides, the backbone of ...
