Viruses (Updated)

The video tutorial explains the nature of the common cold, caused by viruses, and contrasts viruses with living cells. It describes the structure of viruses, including their genetic material and protein coats, and explains the lytic and lysogenic replication cycles. The tutorial also covers complex viruses like HIV, their specific targeting of immune cells, and the challenges posed by viral mutations. Finally, it explores potential positive uses of viruses, such as in gene therapy and as biopesticides, while considering ecological impacts.

How does HIV affect the immune system?

What role can some viruses play in gene therapy?

Discuss the potential ecological consequences of using viral pesticides.
