Test: Virus and Bacteria - JAMB MCQ

Bacteria reproduce asexually through a process called binary fission, where one bacterium divides into two identical daughter cells.

Viruses can have either DNA or RNA as their primary genetic material. They can be classified as DNA viruses or RNA viruses.

Bacteria are larger and more complex than viruses. Bacteria are single-celled organisms, while viruses are much smaller and require a host cell to replicate.

Viruses can be transmitted through various routes, including inhalation of contaminated air, direct contact with infected individuals, and ingestion of contaminated food or water.

Bacteria reproduce through binary fission, which does not involve the production of spores. Some bacteria can form endospores, but this is a survival mechanism rather than a method of reproduction.

Influenza is caused by the influenza virus, which is a viral infection. Tuberculosis, cholera, and typhoid fever are caused by bacteria.

Escherichia coli (E. coli) is a bacterium commonly found in the intestines of humans and animals. HIV, hepatitis B virus, and herpes simplex virus are all examples of viruses.

Viruses cannot reproduce independently and rely on the host cell machinery to replicate. They inject their genetic material into the host cell, which then produces new virus particles.

Viruses are acellular and lack typical cellular structures such as a cell wall, cell membrane, nucleus, mitochondria, or chloroplasts. They consist of genetic material surrounded by a protein coat called a capsid.
