  2. Transfer RNA - Wikipedia

    en.wikipedia.org/wiki/Transfer_RNA

    In the human genome, which, according to January 2013 estimates, has about 20,848 protein coding genes [32] in total, there are 497 nuclear genes encoding cytoplasmic tRNA molecules, and 324 tRNA-derived pseudogenes—tRNA genes thought to be no longer functional [33] (although pseudo tRNAs have been shown to be involved in antibiotic ...

    This process takes many years and is associated with some aging processes involved in oxygen-dependent tissues such as brain, heart, muscle, and kidney. Auto-enhancing processes such as these are possible causes of degenerative diseases including Parkinson's , Alzheimer's , and coronary artery disease .

  4. Wobble base pair - Wikipedia

    en.wikipedia.org/wiki/Wobble_base_pair

    Wobble base pairs for inosine and guanine. A wobble base pair is a pairing between two nucleotides in RNA molecules that does not follow Watson-Crick base pair rules. [1] The four main wobble base pairs are guanine-uracil (G-U), hypoxanthine-uracil (I-U), hypoxanthine-adenine (I-A), and hypoxanthine-cytosine (I-C).

  7. tRNA nucleotidyltransferase - Wikipedia

    en.wikipedia.org/wiki/TRNA_nucleotidyltransferase

    The production of mature tRNAs requires processing and modification steps [1] such as the addition of a 3’-terminal cytidine-cytidine-adenosine (CCA). Since no plant tRNA genes encode this particular sequence, a tRNA nucleotidyltransferase must add this sequence post-transcriptionally and therefore is present in all three compartments.

  9. Peptidyl transferase center - Wikipedia

    en.wikipedia.org/wiki/Peptidyl_transferase_center

    The peptidyl transferase center is a significant piece of evidence supporting the RNA World hypothesis. [2] In prokaryotes, the 50S (23S component) ribosomal subunit contains the peptidyl transferase center and acts as a ribozyme. The peptidyl transferase center on the 50S subunit lies at the lower tips (acceptor ends) of the A- and P- site tRNAs.
