Question

what is the correct sequence of events for creating a trait?

mrna codon → amino acid sequence → protein → phenotype

amino acid sequence → mrna codon → protein → phenotype

phenotype → mrna codon → amino acid sequence → protein

phenotype → protein function → amino acid sequence → mrna codon

Explanation:

In gene expression, mRNA codons (from DNA transcription) determine the amino acid sequence (translation). Amino acids form proteins. Proteins influence traits (phenotype). Other options have incorrect order (e.g., phenotype is the end - result, not the start).

Answer:

mRNA codon → amino acid sequence → protein → phenotype
