Understanding virus research through DNA modification
1:21:37 - 1:29:38 (08:01)
This transcript snippet discusses how researchers can modify viral DNA and put it back into cells to better understand the functional and structural parts of the virus, potentially leading to the creation of antiviral drugs or vaccines.

Researchers use animal models like mice, ferrets, and non-human primates to study viruses like COVID-19 and its transmission.
1:21:37 - 1:22:54 (01:16)
Summary
Researchers use animal models like mice, ferrets, and non-human primates to study viruses like COVID-19 and its transmission. However, no animal model can recreate the severity of symptoms seen in 20% of infected humans, making it difficult to gain insight into controlling the disease.

The recombinant DNA revolution in the 70s made it possible to change DNA in various ways.
1:22:54 - 1:24:06 (01:11)
Summary
The recombinant DNA revolution in the 70s made it possible to change DNA in various ways. The speaker personally made a DNA copy of polio virus and inserted it into a bacteria's DNA to see if it would cause an infection.

Summary
Scientists are able to modify and investigate the function of various genes in RNA viruses by making a DNA copy of the virus, altering it, and putting it back into cells to see the effects on the virus reproduction. This technique has been applied to influenza, as well as other RNA viruses and coronaviruses, for research purposes.

Working with the COVID-19 virus is limited to a few labs because it's a BSL-3 agent, and not everyone has the equipment needed to work with it.

Summary
Working with the COVID-19 virus is limited to a few labs because it's a BSL-3 agent, and not everyone has the equipment needed to work with it. However, there are ways to work with bits of the virus to create a vaccine without needing a BSL-3 lab.
