  2. RNA - Wikipedia

    en.wikipedia.org/wiki/RNA

    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.

  3. 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.

  4. Circular RNA - Wikipedia

    en.wikipedia.org/wiki/Circular_RNA

    In molecular biology, circular RNA (or circRNA) is a type of single-stranded RNA which, unlike linear RNA, forms a covalently closed continuous loop. In circular RNA, the 3' and 5' ends normally present in an RNA molecule have been joined together. This feature confers numerous properties to circular RNA, many of which have only recently been ...

  5. Nucleic acid structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_structure

    Stem-loop or hairpin loop is the most common element of RNA secondary structure. [8] Stem-loop is formed when the RNA chains fold back on themselves to form a double helical tract called the 'stem', the unpaired nucleotides forms single stranded region called the 'loop'. A tetraloop is a four-base pairs hairpin

  6. Messenger RNA - Wikipedia

    en.wikipedia.org/wiki/Messenger_RNA

    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'-triphosphate bond to ...

  7. Silencer (genetics) - Wikipedia

    en.wikipedia.org/wiki/Silencer_(genetics)

    Proper neural folding. Specialized cells called the notochord (A) induces ectoderm above it to become the primitive nervous system. (B) Neural tube forms (C) Gives rise to the brain and spinal cord. (D) Neural crest cells will migrate to different regions throughout the embryo to initiate development of glia, pigments, and other neural ...

  8. Stem-loop - Wikipedia

    en.wikipedia.org/wiki/Stem-loop

    The hairpin loop forms in an mRNA strand during transcription and causes the RNA polymerase to become dissociated from the DNA template strand. This process is known as rho-independent or intrinsic termination, and the sequences involved are called terminator sequences.

  9. Memory transfer - Wikipedia

    en.wikipedia.org/wiki/Memory_transfer

    Memory transfer proposes a chemical basis for memory termed memory RNA which can be passed down through flesh instead of an intact nervous system. Since RNA encodes information [ 1 ] living cells produce and modify RNA in reaction to external events, it might also be used in neurons to record stimuli.
