What is the correct sequence extending down from the phenotype to the genetic unit?

Question

Quizplus · Accepted Answer

The correct sequence from phenotype, which is the observable characteristic, goes down to the genetic unit as follows: Phenotype is determined by proteins, which are made up of amino acids, and the sequence of amino acids is determined by the codons in the DNA. Therefore, the sequence is Phenotype -> Protein -> Amino Acid -> Codon. Option B is the closest to this correct sequence, despite the repetition of "protein," which seems to be a typographical error.
