To explain how cells use DNA to produce proteins, the correct order of steps in the process of protein synthesis is as follows:

  1. Transcription - The process where a specific segment of DNA is copied into mRNA (messenger RNA) by RNA polymerase.
  2. RNA Processing - The mRNA undergoes modifications, including the addition of a 5' cap and a poly-A tail, and splicing to remove introns.
  3. Translation Initiation - The processed mRNA is transported from the nucleus to the ribosome, where it binds to the ribosomal subunits.
  4. Translation Elongation - tRNA molecules bring amino acids to the ribosome, matching their anticodons with the codons on the mRNA to elongate the protein chain.
  5. Translation Termination - The process continues until a stop codon is reached on the mRNA, leading to the release of the newly synthesized protein.
