Question at position 22 What does a ribosome read during translation?mRNAtemplate strand of DNAcoding strand of DNA

Question

BlackTom AI · Accepted Answer

The question asks what a ribosome reads during translation and provides three options to evaluate.
Option 1: mRNA. This is correct because during translation the ribosome travels along the messenger RNA (mRNA) strand, reading its codons to determine which amino acids to add next in the growing polypeptide chain.
Option 2: template strand of DNA. The template (antisense) DNA strand is used by RNA polymerase as a template to synthesize RNA, not something the ribosome reads during translation. The ribosome operates in the cytoplasm on RNA, not on DNA templates.
Option 3: coding strand of DNA. The coding (sense) strand of DNA has the same sequence as the mRNA (except for T versus U), but it is not what the ribosome reads during translation. Translation uses RNA, not direct DNA strands, so the coding DNA strand is not read by the ribosome.
In summary, translation relies on reading the mRNA sequence to guide amino acid incorporation, whereas the DNA strands are involved in transcription and genomic storage rather than direct decoding by the ribosome.
