D
Ribosomal RNA (rRNA)
Verified step by step guidance1
Understand the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein.
Identify the role of each nucleic acid: DNA stores genetic information, mRNA carries the genetic code from DNA to the ribosome, tRNA brings amino acids to the ribosome, and rRNA forms the core of the ribosome's structure and catalyzes protein synthesis.
Recognize that translation is the process where the sequence of nucleotides in RNA is used to synthesize a protein.
Determine which nucleic acid is directly read by the ribosome during translation to assemble amino acids into a polypeptide chain.
Conclude that messenger RNA (mRNA) is the nucleic acid directly translated to synthesize a protein because it carries the codon sequence that dictates the amino acid order.
