Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Mutate their genetic material
Concept:

Viruses exhibit a mix of both living and non-living characteristics, making them unique biological entities positioned at the borderline of life.

Solution:

  • A defining characteristic of life is the presence of genetic material (DNA or RNA) that can undergo replication and mutation.
  • Viruses possess genomes that can mutate, allowing them to evolve and adapt to host defenses.


Why other options are incorrect:

  • Can be crystalized, Lack biosynthetic machinery, No cellular respiration: These are non-living characteristics of viruses.
