Explanation:
The DNA contains many regulatory sequences that are very important, even though they do not code for proteins.
For example, the expression of every gene is regulated by a region called the Promoter. The promoter sequence, located close by the coding region of the gene, usually binds the RNA polymerase (the enzyme that transcribes genes into mRNA) as well as other proteins necessary for transcription,
The promoter sequence, thus, does not itself code for proteins, but is essential for transcription and must be highly conserved so that the RNA polymerase can find it.

Based on the cladogram, the organisms that are most related are A and C since they had the most recent divergence.
<h3>What is a cladogram?</h3>
A cladogram is a diagram which is tree-like showing similarities and differences among organisms as a result of evolutionary changes that occur in the organisms.
In a cladogram, the most similar organisms have the most recent branching along the cladogram.
Based on the description of the cladogram, the most recent branching occurred between A and C.
Therefore, based on the cladogram, the organisms that are most related are A and C.
