Multiple RNA molecules are important in translation: mRNA, tRNA, and rRNA. Which of the following is most likely to slow the production of a single protein in the cytoplasm? Downregulation of genes encoding tRNA components. An increase in the synthesis of the 80S ribosomal proteins important in ribosomal translational initiation. Recruitment of RBPs that promote RNAse degradation to the 3’UTR of the mRNA transcript. Mutations in mitochondrial tRNAs important in the synthesis of mitochondrial proteins.

RNA may be divided into coding RNA and non-coding RNA. Match each term in Column I to the correct group in Column II. Options from Column II can be used more than once. And please explain their roles in each item in column I. Column I: mRNA rRNA tRNA transfer-messenger RNA (tmRNA) small nuclear RNA (snRNA) small nucleolar RNA (snoRNA) small cytoplasmic RNA (scRNA) siRNA (short interfering RNA) miRNA (microRNA) long non-coding RNA (lncRNA) Column II coding RNA non-coding RNA

Place the following steps of TRANSLATION in the correct order for EUKARYOTES. The ribosome reaches a stop codon. A release factor binds and causes the release of the new polypeptide, along with the mRNA. The ribosome dissociates. v Acharged tRNA with a matching anticodon binds the mRNA codon in the A site. ✓ The ribosome moves exactly 3 nucleotides toward the 3* end of the mRNA. The small ribosomal subunit uses rRNA to bind to the Kozak sequence, which places...
