The mRNA, small ribosomal subunit, and large ribosomal subunit form a tightly assembled complex prior to the binding of the initiator tRNA

True

False

As important as the rRNA components are to the structure of the ribosome, it is the ribosomal proteins which actually catalyze the formation of peptide bonds.

Answer #1

Answer:

1). False

Explanation:

First binding of the initiator tRNA to small ribosomal subunit. Then it binds to mRNA and then large ribosomal subunit binds them.

2). False

Explanation:

The formation of the peptide bond is catalyzed by peptidyl transferase, an RNA-based enzyme that is integrated into the large ribosomal subunit.

    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.
