Final answer:
Viruses have unique genetic properties; their genomes can be DNA or RNA, single or double stranded, and sometimes are segmented, leading to high variability and challenges in vaccine development.
Step-by-step explanation:
Three unique things about the genetic material found in viruses include:
- Viruses may use either DNA or RNA as genetic material, unlike most living organisms which only use DNA.
- The genetic material in viruses can be either single- or double-stranded, and may also be either linear or circular in structure.
- Some viruses have segmented genomes, which can lead to high variability and rapid evolution, making it difficult to create effective vaccines.
Glycoproteins also play a critical role in allowing viruses to attach to host cells, which is vital for the infection process.
