E) RNA of the chromosomes

Question

Quizplus · Accepted Answer

The instructions for protein synthesis are stored in the DNA of the chromosomes, which serve as the template for the synthesis of messenger RNA (mRNA). The mRNA codons determine the order of amino acids in a protein, leading to the assembly of a specific protein. Transfer RNA (tRNA) contains anticodons that recognize specific codons on the mRNA and transport the corresponding amino acid to the growing protein chain on the ribosome. Ribosomes provide the site for protein synthesis, but do not store the instructions themselves. RNA of the chromosomes refers to the transcription products of DNA, which include mRNA, ribosomal RNA (rRNA) and transfer RNA (tRNA), but the primary storage of genetic information is in the DNA itself.
