Nucleic acid of viruses is known as capsid
|
|
Viruses possess their won metabolic system
|
|
All viruses contain both RNA and DNA
|
|
Viruses are obligate parasites
|
Detailed explanation-1: -All viruses are obligate parasites, i.e., they lack metabolic machinery of their own to generate energy or to synthesize proteins, hence they depend on the host cells to carry out these vital functions.
Detailed explanation-2: -Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat. Viruses may be viewed as mobile genetic elements, most probably of cellular origin and characterized by a long co-evolution of virus and host.
Detailed explanation-3: -The correct answer is B. Viruses do not eat food, but they live inside the cells of their hosts.
Detailed explanation-4: -Viruses use the machinery of the host cells to reproduce. They do not have cell organelles such as Golgi complex, mitochondria, lysosomes, ribosomes etc. hence, they cannot reproduce or live separately. Therefore they are called obligatory intercellular parasites.
Detailed explanation-5: -Viruses do not infect bacteria, fungi, and algae.
