SUMMARY

Viruses and bacteria are fundamentally different entities in biology. A virus consists of a snippet of DNA or RNA enclosed in a protein shell, while bacteria are fully functional cells capable of independent life. Key distinctions include that bacteria possess ribosomes for protein synthesis and polymerases for DNA replication, whereas viruses rely on host cellular machinery for these processes. Additionally, bacteria reproduce through methods such as fission, while viruses assemble within host cells. Bacterial genetic material is always DNA-based, whereas viruses can have single or double-stranded DNA or RNA.

PREREQUISITES

Virus and Bacteria?

What is the difference between virus and bacteria? What are the advantages and disadvantages of them?
 
Biology news on Phys.org


A virus is just a snippet of DNA or RNA enclosed in a shell. A bacteria is basically a fully functional cell. Advantages and disadvantages? Ummmm...for what?

Anyway, you can read the wiki on them for a much fuller descripton.
 


Viruses and bacteria differ in several respects.

Bacteria have ribosomes and can therefore make proteins on their own, viruses can't

Bacteria have polymerases for making copies of their own DNA, most viruses hijack cell-
machinery for DNA synthesis (though some viruses can transcribe their own
genetic material)

Bacteria reproduce through fission, budding, etc while viruses are built in the cell

Bacterial genetic code is always DNA based while viruses can be single or double stranded
DNA or RNA viruses

Bacteria have a metabolism, while viruses don't

Basically, viruses are very, very simple forms of life. They lack many of the necessary components for replication, which is why they must infect, hijack, and use a host's cellular machinery for their own purposes.
