what does a virus inject into a cell

A virus injects its genetic material —its nucleic acid (DNA or RNA)—often along with a few helper enzymes, into the host cell. The protein shell (capsid) usually stays outside or is broken down after entry, while the viral genome inside the cell then hijacks the cell’s machinery to make more viruses.

What gets injected

• Most viruses deliver nucleic acid (viral DNA or RNA) into the cell, not whole virus particles.

• Some viruses also bring enzymes (like integrases or polymerases) that help copy or insert their genome into the host’s DNA.

What happens next

• Once inside, the viral genome uses the cell’s ribosomes and enzymes to make viral proteins and more copies of its genome.

• These components assemble into new virus particles, which then leave the cell, often damaging or killing it in the process.
