Functions & Roles Of rNa Performing As A Ribozymes
1. Cutting (cleaving) molecules that are, or will, become rNA or protein. We have already learned rNA has a nucleus called a Nucleoid. We also learned one of the meanings of nucleus is “to cut in pieces.” The form of the word we used was Sekar. Sekar is Sakar is (Sa + Kar).One of the meanings of Sa is ”to tie.” 2. Tying (ligating) molecules that are, or will, become rNA or protein. In some ribozyme-catalyzed reactions, the rNA cutting and tying processes are linked and called splicing. Splicing is sometimes assisted by a protein enzyme when ribozymes catalyze chemical reactions in the nucleus. Sometimes splicing is carried out by protein enzymes only. The nature of ribozymes also performing “joining” operations is in keeping with the two truths. Anything that has the potential to do one thing, also has the potential to do the opposite. Thus, a genetic potential to cut is paired with a genetic potential to join.
Tek is (T + Ka). Teka means to touch, attach, join, adhere, mix[splice], cleave, multiply, cross, twist, intertwine. (BB 50/62 and 218/230) 3. Self-Splicing Some partially complete rNA compounds being assembled into rNA, have their own rNA that functions as a ribozyme. After splicing is complete, the ribozyme is broken down. 4. Self-Cleaving and Self-Splicing Transesterification takes place in eukaryote organelles, prokaryotes and viruses. 5. Hydrolysis in eukaryote organelles, prokaryotes and some amoeba. 6. Peptidyl transfer (peptide bond) in ribosomes of prokaryotes and eukaryotes. 7. Trans-splicing transesterification in nucleus of eukaryotes. 8. Fine-tuning messenger rNA life cycles. 9. Serve as a template (mini-trueprint/blueprint) upon which the reactants are brought together and properly oriented to favor the completion of the desired change.
