👉 A submicroscopic, non-cellular structure consisting of a core of DNA or RNA surrounded by a protein coat, that requires a living host cell to replicate, and often causes disease in the host organism.
Alright class, settle down, let’s take a look today! You've got your dictionaries open, good work indeed, Let’s break down this word, plant a learning seed. The dictionary says “virus,” quite a tricky name, But let’s unpack it slowly, like a scholar’s game. It starts with "submicroscopic," small as you can see, Smaller than a cell, incredibly tiny and free! “Non-cellular” means it's not a cell at all, Just a package of secrets, answering nature’s call. Inside, there’s “DNA or RNA,” a genetic code bright, Like instructions for building, with all its might! And around that core, a "protein coat" you find, Protecting the message, cleverly designed. Now listen closely, this is key to understand: It needs a living host cell, close at hand. To “replicate,” meaning copy itself with glee, Like multiplying quickly, for all the world to see! And often, sadly, it causes disease you know, Making someone feel poorly, putting on quite a show! So, in short, a virus is a tiny, clever guest, That needs a host cell to live and to test. Do you have any questions about this little fright? Let’s discuss it now, with all your insight!
