Lesson 1: Why do we name viruses?
Having a name matters to prevent the use of other names that can be inaccurate or stigmatising. It also gives us a standard format to use for any future virus…
Lesson 2: How do we classify viruses?
Viruses are classified based on a combination of several criteria that take into account their morphology, nucleic acid type, mode of replication,host organisms, evolutionary relationships and the type of disease…
Lesson 1: Why Do Classify Viruses?
The International Committee on Taxonomy of Viruses (ICTV) is responsible for classifying viruses, which is based on factors like morphology, genome type, replication strategies, and evolutionary relationships. This system provides…
Topic 5: Classification of viruses
A. VIDEOS Viral classification Classification of viruses Baltimore classification of viruses-1 Baltimore classification of viruses-2 Virus structure and classification B. LEARNING OUTCOMES By the end of this lesson, students should…
Lesson 5: Segmented and Multipartite Virus Genomes
Segmented and multipartite viral genomes are both types of viruses where the genetic material is split into multiple parts, but they differ in how these parts are packaged and distributed…
Lesson 3: Characteristics of Viral DNA genomes
Viral DNA genomes come with distinct characteristics that define their structure, replication strategy, and how they interact with the host. Here are the key characteristics of viral DNA genomes: 1.…
Lesson 2: Information is encoded or not encoded in viral genomes
Viral genomes are small and compact, yet they carry essential genetic information required to infect host cells and produce new virus particles. Because of limited genome size, viruses encode only…
Lesson 1: Nature of viral genomes
Viruses possess unique genetic systems that distinguish them from all cellular organisms. Unlike cells, viruses contain only one type of nucleic acid (DNA or RNA) and rely on host cellular…
