The virus doesn't enter the cell at first think of it as a corn dog. The stick part merely attaches to the cell wall. The coating on the corn dog would be the protein shell protecting the DNA of the virus which equates to to the weenie inside the protein shell, The virus then causes the cells endoplasmic reticulum to synthesize new viruses inside the cell until enough are replicated to over fill the cell and the cell wall ruptures releasing newly synthesized viruses to attack other cells.
Granted, but for a cure to work it has to kill the virus no matter how far it has permeated the cell...so it's easier to to just say it has to kill the virus inside the host cells. The explanation I typed was long enough already ...
llama44 I did my best to really make the process as simple as I could from a cell biology course and a biochemistry course I took in 1972 some things have changed of course in our understanding of viruses since then. The video Marie-AnneLiz referred to is actually very similar to what I learned then about viruses in general and I really recommend the video for those wanting more accuracy in their understanding of this specific virus. It was a very good video. Thank you both for your inputs.
Yes that guy is qualified and he is really good at making it fun to watch.
Zach attended Misericordia University where he received his Bachelors of Science degree in Biology and a minor in chemistry.
