The diagram above shows how these steps might occur for a virus with a single-stranded RNA genome. You can see real examples of viral lifecycles in the articles on bacteriophages (bacteria-infecting …

A diagram of a typical viral infection cycle. The diagram shows virus attachment (1), the entry of genetic material into the host cell (2), replication of the viral genetic material (3a) and proteins (3b), self …

A typical viral infection cycle includes attachment to a host cell, entry of the virus’s genetic material, viral replication, self-assembly, and release. Created by Sal Khan.

One of the craziest-looking (to me, at least) is the Ebola virus, which has a long, thread-like structure that loops back on itself. A more "standard-looking" virus, chikungunya, is shown below for …

May 10, 2016 · First, we’ll examine the structure, life cycle, and transmission mode of Zika virus, seeing how it infects cells. Then, we’ll look at the effects of Zika on humans, as well as the prospects for …

The phospholipids of a eukaryotic or bacterial membrane are organized into two layers, forming a structure called a phospholipid bilayer.

So let's think about the things that define viruses. There's four things we're going to look at. First, they're really, really small. So, size. The virus is about that big. Compared to that tiny virus, this would be the …

A bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material.
