Some infected cells, such as those infected by the common cold virus known as rhinovirus, die through lysis (bursting) or apoptosis (programmed cell death or “cell suicide”), releasing all progeny virions at once. Both of these organelles have their own DNA and their own ribosomes that do not match the rest of the cell.
