Understand the Problem

The question is asking which characteristic shared by all organisms allows for nucleotide sequence comparisons based on homology. It provides several options related to cellular and molecular biology.

Answer

DNA bases

The final answer is DNA bases.

Answer for screen readers

The final answer is DNA bases.

More Information

Nucleotide sequences can be compared in all organisms due to shared DNA bases, which are the fundamental components of genetic material.

Tips

A common mistake is confusing cellular structures with molecular ones. The question focuses on genetic homology, which is molecular.
