Question

every trait you see on an organism is a result of that organisms dna instructing the organisms cells. how does the information stored in dnas nucleotides translate into traits such as eye color and ear shape? (1 point)
traits are determined by the presence or absence of lac operons along a series of nucleotides.
traits are determined by codons that are broken apart to form proteins.
traits are determined by a group of enzymes known as dna helicases.
traits are determined by proteins that are built according to the instructions stored in genes.

Explanation:

Genes (segments of DNA) contain instructions. Through transcription and translation, these instructions are used to build proteins. Proteins play crucial roles in determining an organism's traits like eye color and ear shape. Lac operons are related to gene regulation in bacteria (not general trait determination). Codons are part of mRNA (from DNA) and are used in protein - building (not "broken apart"). DNA helicases are for DNA unwinding during replication (not trait determination).

Answer:

Traits are determined by proteins that are built according to the instructions stored in genes.
