Viruses Quiz
Embark on a viral journey to uncover the microscopic invaders lurking in the world around us. Dive into the essence of what viruses are made of, exploring their genetic heart and protective protein coat. Decode how they cunningly enter human cells and replicate themselves, commandeering the host's machinery. Discover the structural complexities that distinguish them from other pathogens and the ingenious ways humans have developed vaccines and antiviral drugs to combat their spread. Whether it's through endocytosis or the battle for our ribosomes, prepare to be fascinated by the life cycle of these enigmatic entities and the defence mechanisms we've evolved to protect ourselves against them. This quiz is your microscope to the viral verses of biology!
