  2. RNA - Wikipedia

    en.wikipedia.org/wiki/RNA

    In the cytoplasm, ribosomal RNA and protein combine to form a nucleoprotein called a ribosome. The ribosome binds mRNA and carries out protein synthesis. Several ribosomes may be attached to a single mRNA at any time. [27] Nearly all the RNA found in a typical eukaryotic cell is rRNA. Transfer-messenger RNA (tmRNA) is found in many bacteria and ...

  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. 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 ] and living cells produce and modify RNA in reaction to external events, it might also be used in neurons to record stimuli.

  5. 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 ...

  6. Neural plate - Wikipedia

    en.wikipedia.org/wiki/Neural_plate

    The progenitor cells that make up the precursors to neural tissues in the neural plate are called neuroepithelial cells. [citation needed] Stretched over the notochord, the ectodermal cells on the dorsal portion of the embryo are ultimately the ones that form the neural plate. Approximately half of those cells will be induced to remain ectoderm ...

  7. 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 ...

  8. Nucleic acid quaternary structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_quaternary...

    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

  9. Eukaryotic translation - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_translation

    Translation is one of the key energy consumers in cells, hence it is strictly regulated. Numerous mechanisms have evolved that control and regulate translation in eukaryotes as well as prokaryotes. Regulation of translation can impact the global rate of protein synthesis which is closely coupled to the metabolic and proliferative state of a cell.
