There are two main types of pathogens we will be focusing on in this series. The first was bacteria, and we just wrapped up a good amount of information on those. The next is viruses. These little things are much tinier than bacteria, and they are so simple in structure that we technically don't even consider them to be living organisms. But ...

Viruses are transferred as particles, known as virions. Once the virion enters a host cell, it disassembles and the viral genome begins to interfere with cellular processes. The first stage of the intracellular phase of the viral replication cycle is cell entry. Outline: 00:00 - Viral replication cycle 00:30 - RNA viruses 04:03 - DNA viruses ...

Compared to eukaryotic and even prokaryotic cells, viruses are much smaller and simpler in structure. Lacking the structures and metabolic machinery found in a cell, a virus is an infectious particle consisting of little more than genes packaged in a protein coat. Are viruses living or nonliving? Viruses contains both living and non living ...

Positive-sense RNA viruses (or +RNA viruses) are a type of viruses that have a single-stranded RNA genome which can act as messenger RNA (mRNA) and can be directly translated by the host cell's ribosomes into viral proteins. These viruses are called "positive-sense" because their RNA genome has the same sequence as the viral mRNA, which means ...
