Answer 2

Answer:

The correct answer to this question is DNA.

Explanation:

Viruses only contain one type of nucleic acid—DNA or RNA—and never both, making them smaller and simpler to build than unicellular microorganisms. Since viruses lack ribosomes, mitochondria, or any other organelles, their only source of energy and protein synthesis is their cellular hosts. They only reproduce within the cells of the host they infect.

In contrast to other microorganisms, many viruses can reproduce themselves from a single nucleic acid molecule—their nucleic acid—in appropriate cells. Like a bacterial spore, the virus particle is metabolically inert outside of a susceptible cell; However, when it replicates within a cell, it exhibits all of life's characteristics.

The filterable viruses are the new category of microorganisms. The filtration studies has shown that virus particles (virions) range from about the size of the smallest unicellular microorganisms (300 nm) down to objects little bigger than the largest protein molecules (20 nm).The capsid, a protein coating, surrounds a single nucleic acid molecule known as the virion in simpler viruses; The nucleocapsid is made up of the capsid and the nucleic acid inside.
