Answer:
The correct answer is mRNA.
Step-by-step explanation:
Messenger RNA is the RNA that contains genetic information in terms of genetic code. The mRNA is formed from the transcription of DNA.
mRNA contains the nucleotide sequence and each triplet sequence in the mRNA codes for an amino acid and called genetic code. The process of formation of amino acid or protein is called translation. This protein is expressed in the phenotype.
Ribosome binds to the mRNA and allow the tRNA to attach to the triplet codon present on mRNA and add specific amino acid to the growing polypeptide chain. Therefore the right answer is mRNA.
