Introduction: Sabotage Inside Our Cells Viruses are invaders that sabotage our cells – Viruses have genetic material surrounded by a protein coat and, in some cases, a membranous envelope – Viral proteins bind to receptors on a host’s target cell – Viral nucleic acid enters the cell – It may remain dormant by integrating into a host chromosome – When activated, viral DNA triggers viral duplication, using the host’s molecules and organelles – The host cell is destroyed, and newly replicated viruses are released to continue the infection Copyright © 2009 Pearson Education, .
