D
DNA polymerase and mRNA
Verified step by step guidance1
Understand the process of translation: Translation is the process by which ribosomes synthesize proteins using mRNA as a template.
Identify the key components involved in the initiation stage of translation: These include the ribosomal subunits, mRNA, and initiator tRNA.
Recognize the role of each component: The small ribosomal subunit binds to the mRNA, the initiator tRNA carries the first amino acid (usually methionine), and the large ribosomal subunit completes the assembly to form a functional ribosome.
Eliminate incorrect options: DNA and DNA polymerase are not involved in translation, and RNA polymerase is involved in transcription, not translation.
Conclude with the correct components: The initiation stage of translation requires the assembly of ribosomal subunits, mRNA, and initiator tRNA.
