How do viruses cause disease (the effect(s) on host cells or tissues that cause disease)? Name a specific virus and the disease it causes and how it causes the disease. This is not about the stages of the virus life cycle. All viruses are obligate ...
Explain how viruses can transform human cells, leading to the formation of tumors. What kind of biological and epidemiological evidence would you need before you were comfortable saying a specific virus caused cervical cancer? What is the role of viruses in...

The structure of the lungs exposes them to viruses and bacteria from both the air and the blood. Macrophages are immune cells that, among other things, protect the lungs from such attacks. But under certain conditions, lung macrophages can also contribute to severe lung dis...

You have analyzed the base composition of the genetic material in a virus and found the following: 32% adenine, 17% uracil, 18% guanine, 33% cytosine. Which of the following best describes the structure of this viral genome? • Single-stranded D...
Even as the structure of SARS-CoV-2 changes with different variants of the virus (gray), the J08 antibody (blue) can still bind it, Scripps researchers showed. Credit: Scripps Research Last year, scientists at Scripps Research and Toscana Life Sciences studied the blood of 14 COVID-19 surv...
In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers at Karolinska Institutet in Sweden describe how immune cells called macrophages develop in the lungs and which of them may be behind severe l
