What allows the production of viral copies when retroviruses are used as a vector targeting dividing somatic cells?

Question

Quizplus · Accepted Answer

When retroviruses are modified, they lose the ability to replicate by themselves. Packaging cells provide the necessary genes retroviruses need for replication. Answer A is incorrect because transduction is the process in which DNA is transferred to another cell which enables the target cell to begin expression. Answer C is incorrect because modified retroviruses are incapable of replicating by themselves so viral invasion would not lead to viral copies. Answer D is incorrect because modification reduces retroviruses ability to replicate.
