Viruses are tiny biological 'pirates' because they invade cells, plunder their nutrients and use their chemical reactions to reproduce. Soon after, the descendants of the invaders are transmitted to other cells, causing devastating damage. According to the text, it is correct to say:

• Viruses use their own metabolism to destroy cells.

• Viruses do not have their own metabolism.

• Viruses always result from genetic modifications of the host cell.

• Viruses are genetic transcriptions induced by viruses that degenerate chromatin in the host cell.

All viruses are made up of:

• DNA and proteins.

• Amino acids and water.

• Nucleic acids and proteins.

• RNA and proteins.

Whereas RNA vaccines produce antigens that stimulate the immune system, the development of RNA vaccines has generated:

• alteration of the human genome to increase resistance to viruses.

• development of viruses expressing restriction enzymes.

• production of inactivated viruses to stimulate the immune system.

• synthesis of a synthetic mRNA responsible for the production of a viral protein.

About viruses, what is the incorrect alternative

• They are acellular and prokaryotes.

• Your genetic material can be DNA or RNA.

• They do not have their own metabolism; therefore, they are obligate intracellular parasites.

• Retroviruses carry RNA and the enzyme reverse transcriptase

Made up of proteins that, in addition to protecting the viral nucleic acid, allow the virus to recognize and attack the type of cell suitable for hosting it:

• viral nucleus

• lipid envelope

• capsid

• DNA
