Yes, viruses are composed of organic molecules.
Viruses, although not considered living organisms, are essentially assemblies of organic molecules. They consist of genetic material (either DNA or RNA) encased in a protein coat called a capsid. These components – nucleic acids (DNA or RNA) and proteins – are fundamentally organic molecules.
Here's a breakdown:
- Nucleic Acids (DNA or RNA): These are complex organic polymers made up of nucleotides. Each nucleotide contains a sugar, a phosphate group, and a nitrogenous base. These molecules carry the genetic information of the virus.
- Proteins: The capsid, and any other proteins associated with the virus, are made up of amino acids, which are organic compounds containing carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
While viruses are made of organic molecules, it's important to note that their lack of cellular structure and independent metabolism leads to them not being considered living organisms. They require a host cell to replicate and carry out their biological functions.
In summary, viruses are fundamentally organic entities due to their composition of nucleic acids and proteins, but their non-cellular nature means they are not classified as living organisms.
