Answer #1

Ricin is extracted from castor plant (Ricinus communis) it inhibits the protein synthesis mechanism by irreversibly degrading the ribosomes; making ribosomes unavailable for protein synthesis. It specifically hydrolysis the glycosidic bond in the larger subunit of the ribosome, namely 28s rRNA; which completely degrades or breakdown ribosomes. This leads to incomplete protein synthesis.

    Tetracycline inhibits protein synthesis by which mechanism? It interacts with the small ribosomal subunit, blocking access of the aminoacyl-tRNA to the mRNA-ribosome complex. It binds to the 305 subunit and distorts its structure, interfering with the initiation of protein synthesis. It binds irreversibly to a site on the 50S subunit of the bacterial ribosome, thus inhibiting translocation. It inactivates the eukaryotic elongation factor, eEF-2, thus preventing translocation.

Which of the following general statements pertaining to their functions and mechanisms of action is/are true? A. Some of these factors bind tRNA and facilitate their binding to the appropriate sites in the ribosome. B. Some of these factors bind GTP and rely on their hydrolysis to GDP to signal the correct interactions. O C. These...

    QUESTION 15 Antibiotics have been very useful in elucidating the steps of protein synthesis. If you have an artificial mRNA with the sequence 5'-AUGGGGGGGGGG..., it will produce the following peptide in a cell-free, protein synthesizing system: fMet-Gly-Gly-Gly-Gly.... In your search for new antibiotics, you find one that blocks protein synthesis. When the same artificial mRNA is added to the cell free system with the antibiotic, only the dipeptide product: fMet-Gly is produced. Which step in protein synthesis could this antibiotic...

    5) Translation was originally sorted out using a variety of inhibitors of protein synthesis Inhibitors tend to interrupt the process at a particular step and a population of translating ribosomes will all stop in the same state. An allied technique is to identify temperature sensitive mutations in various accessory factors. When the population of ribosomes is shifted to the restrictive temperature, ribosomes will stall when they need the function of the mutant protein to continue By analyzing the structure of...

    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...
