The synthesis of a protein requires that the amino acids that constitute the growing polypeptide chain be covalently linked to the amino acid attached to the tRNA at the aminoacyl site of the ribosome. Which of the following catalyses this reaction? Options: the aminoacyl tRNA synthetase eEF2 eEF1-GTP a large ribosomal RNA the initiator tRNA met
Place the steps below in the correct order to accurately reflect the steps by which a secretory protein is co-translationally imported into the lumen of the endoplasmic reticulum: As the polypeptide elongates and translocates into the ER, the signal peptidase cleaves the signal peptide. The SRP binds the SRP receptor, directing the ribosome to dock on the ER membrane. Termination of translation, results in the release of the polypeptide into the ER lumen, release of the ribosome from the ER membrane, and closing of the channel. The signal recognition particle (SRP) binds to the signal sequence on a newly synthesized polypeptide and stalls translation. The channel in the ER membrane opens and the polypeptide is inserted into the ER lumen. The SRP is released. A.6-4-2-3-1-5 B.4-2-5-1-3-6 C.3-1-6-2-4-5 D.1-2-3-4-5-6 E.2-6-1-5-4-3
During the biosynthesis of ribosomes, rRNA synthesized in the (fill in) Nuclear membrane nucleolus Cytoplasm Nuclear pore complex And Ribosomal proteins are assembled together into the rirbosomal subunits which are then shipped to the cytoplasm where mature ribosomes are finally assembled. Free ribosomes are localized in the cytoplasm and synthesize cytoplasmic proteins such as [ans2].

The following is the only intron sequence of a gene that will be excised during the maturation of the mRNA. But it is not spliced in some tissues, where alternative splicing pattern is seen. Will the amino acid of its protein product following this sequence change? Explain with an example. ATGATAGCCAGACTCGCA
Hemophilia in the Russian royal family was caused by defective protein involved in blood clotting (factor IX). This defective protein was caused by a mutation that altered the splicing of the exons. This genetic change in the splicing pattern created a new stop codon in the mRNA for factor IX. What effect might this new stop codon have on the primary and tertiary levels of the mutant factor IX protein (compared to the native or wild-type protein).

Renata enzymatically conjugates a 14C-labeled cysteine to a transfer RNA (ERNA), with a UGU anticodon. Then, she chemically modifies the cysteine group to valine. Finally, she adds the altered aminoacyl-tRNA to a protein-synthesizing system containing normal components and a messenger RNA (MRNA) with the sequence 5'-UUUUGCCAUGUUUGUGCU-3'. What is the sequence of the radiolabeled peptide Renata produces? Enter your answer using three-letter abbreviations for each residue, separated by single hyphens. You may need to reference a codon table. radiolabeled peptide sequence: Phe-Cys-His-Val-Ala-Ala Incorrect

Another thalassemic patient had a mutation leading to the production of an mRNA for the β chain of hemoglobin that was 900 nucleotides longer than the normal one. The poly(A) tail of this mutant mRNA was located a few nucleotides after the only AAUAAA sequence in the additional sequence. Propose a mutation that would lead to the production of this altered mRNA.
