The correct order of the steps involved in protein synthesis is:
- Locate the start, stop, and other codons on the mRNA.
- Transcribe the DNA to create the mRNA.
- Match the mRNA codons to their tRNA anticodons and the attached amino acids.
- Perform dehydration synthesis to build the amino acid chain in the ribosome.
- Identify the antisense strand of the DNA within the cell nucleus. (This step is not directly related to protein synthesis.)
What are the gene processes?
Locate the start, stop, and other codons on the mRNA.
This step involves analyzing the mRNA sequence to identify the start codon (AUG), stop codons (UAA, UAG, UGA), and coding sequences (codons) that specify amino acids.
Transcribe the DNA to create the mRNA.
Once the start codon is located, RNA polymerase binds to the promoter region of the DNA and transcribes the coding sequence into a complementary mRNA strand.
Match the mRNA codons to their tRNA anticodons and the attached amino acids.
Ribosomes move along the mRNA, and tRNA molecules with anticodons complementary to the mRNA codons bind to the ribosome. Each tRNA carries a specific amino acid corresponding to its anticodon.
Perform dehydration synthesis to build the amino acid chain in the ribosome.
As the ribosome moves along the mRNA, peptide bonds form between adjacent amino acids carried by the tRNA molecules, creating the growing polypeptide chain.
Identify the antisense strand of the DNA within the cell nucleus.
This step is not directly involved in protein synthesis. While the antisense strand exists in the DNA molecule, it doesn't participate in the transcription process that leads to mRNA and subsequent protein synthesis.
Complete question:
