Question
- Which of the following is considered acellular?Aspergillus fumigatusMycobacterium tuberculosisSulfolobus islandicusHepatitis B virus
Solution
The Hepatitis B virus is considered acellular. This is because it does not have cellular structure. Viruses are generally considered acellular because they lack the characteristics of living cells, such as a nucleus, cytoplasm, and organelles. Instead, they consist of a protein coat and a core of genetic material. They are also unable to reproduce on their own and must infect a host cell to do so.
