SSC MTS EXAM

Detailed explanation-1: -Obligate intracellular parasites cannot reproduce outside their host cell, which means that the parasite’s reproduction is entirely reliant on intracellular resources.

Detailed explanation-2: -Viruses are obligate parasites in that they can only replicate within a living host cell. Thus the science of virology is largely dependent upon the requirement to be able to grow and propagate such host cells.

Detailed explanation-3: -An obligate parasite cannot complete its life cycle without a suitable host. Viruses infect a cell, take the machinery of the cell and replicate. Hence, they are intracellular obligatory parasites.

Detailed explanation-4: -All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions. Once inside a cell, viruses have genes for usurping the cell’s energy-generating and protein-synthesizing systems.…
