Viruses _____.
A)manufacture their own ATP and carbon-containing compounds like proteins and nucleic acids in order to survive
B)use the host cell's machinery to make more copies of themselves and to make viral proteins
C)need the host cell's machinery to make more copies of themselves before they can synthesize their own proteins
D)cannot reproduce or synthesize cell products without the host cell's machinery,but once their proteins are produced they are capable of metabolizing food to produce ATP
E)use their own protein-synthesizing machinery to make more viral proteins that are used to assemble more copies of themselves

Question

Quizplus · Accepted Answer

Viruses are obligate intracellular parasites that rely on the host cell's machinery to carry out their replication and protein synthesis. They lack the metabolic machinery required for ATP and carbon-containing compound synthesis, which is why they need to hijack the host cell's machinery to replicate themselves. Viruses use the host cell's ribosomes, enzymes, and nutrients to synthesize viral proteins and RNA/DNA molecules, and they assemble new virus particles using these components. Therefore, choice B is the most accurate answer.
