Tetracyclines are a class of broad-spectrum antibiotics used in the management and treatment of a variety of infectious diseases by inhibiting translational machinery in bacteria.
Reason R: Tetracyclines inhibit protein synthesis in bacteria by blocking the A site on the ribosome, preventing the binding of aminoacyl- tRNAs.

QUESTION ID:74

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Vesicular transport is the predominant mechanism for exchange of proteins and lipids between membrane-bound organelles in eukaryotic cells. Golgi-derived vesicles are involved in several vesicular transport steps, including bidirectional transport within the Golgi and recycling to the ER. A protein X is a type II transmembrane protein (N-terminus in the cytosol) localized to the Golgi. If you add a KDEL sequence to its N-terminus, the mutant protein will localize in the Golgi.
Reason R: ER luminal proteins, especially those present at high concentrations, can be passively incorporated into COPII vesicles and transported to the Nucleus. Many such proteins bear a C-terminal KDEL (Lys-Asp-Glu-Leu) sequence that allows them to be retrieved. The KDEL receptor, located mainly in the nuclear network, binds proteins bearing the KDEL sorting signal and returns them to the ER. This retrieval system prevents depletion of ER luminal proteins such as those needed for proper folding of newly made secretory proteins.
