Es
viruses, although not considered to be alive, attack host cells and cause disease. the attack of a host cell is necessary for the
virus to survive for all of the reasons listed except one. that is
they cannot synthesize proteins because they lack ribosomes and must use
the ribosomes of their host cells to translate viral messenger rna into new eminate
proteins
they cannot produce or store energy in the form of atp and have to get
their energy from the host cell
they parasitize the host cell for basic molecules like amino acids,
nucleotides, and lipids,
they lack dna/rna so they must use the dna of the host cell

The correct answer is : They lack DNA/RNA so they must use the DNA of the host cell.

Explanation:

In general, Viruses are composed of two major parts, a genetic material - DNA or RNA (depending upon the type of virus) and a capsid protein coat that encloses and protects the genetic material.Without a genetic material no matter can be considered as living as there will be no multiplication and replication possible.Viruses need the host for its metabolism, replication and multiplication process.After infection, they hijack the cells protein-synthesising machinery, the ribosomes, and utilise the host cell's energy (ATP) for synthesising their own proteins encoded in their genetic material.They utilise the basic components of the host cell like amino acids, nucleotides and lipids for synthesising their own proteins, replicating and producing multiple copies of their genetic material and also producing their coat proteins and lipids.This way the infection-causing virus produces multiple virion particles that exit the infected host in search for new host and repeating this life-cycle.
