Metabolic manipulations in virus-infected cells

2 Comments / Basic virology, Information / By

The large quantities of viral macromolecules and virus particles that are produced in an infected cell impose heavy demands on the host. Synthesis of the building blocks of a virus particle – nucleotides, amino acids, and sometimes fatty acids – requires energy, typically in the form of ATP. Synthesis of viral proteins and genomes, and …
