The components that are found in the cells of all living organisms from the available options are Cytosine and Guanine.
All living cells contain important biomolecules such as lipids, proteins, nucleic acids, etc.
Nucleic acids are made of 3 major components:
- pentose sugars
- phosphate groups
- nitrogenous bases
The nitrogenous bases could be:
- purines: such as Adenine and Guanine
- pyrimidines: such as Cytosine and Thymine or Uracil
Thus, by all means, no living organisms can do without possessing Cytosine and Guanine because all living organisms have nucleic acids.
