Answer :
The conclusion that best describes the data in the table is that organisms have different proportions of bases in their DNA. Option B.
DNAs of organisms
The DNA of all living organisms is similar in chemical composition. The basic chemical components are:
- Deoxyribose sugar
- Purine and pyrimidine bases
- Phosphate groups
Talking about the bases, organisms' DNAs vary in terms of the percentage of purine and pyrimidine bases they contain.
The purine bases are Adenine (A) and Guanine (G). The pyrimidine bases are Cytosine (C) and Thymine (T).
Even though the percentage of purine and pyrimidine bases varies from organism to organism, the amount of Adenine is always equal to that of Thymine while Guanine is always equal to Cytosine in every organism.
This is known as Chargaff's rule.
Thus, looking at the data in the table, the best description is that organisms have different proportions of bases in their DNA.
