Question

most proteins last 2 days or less in the body. cells must constantly undergo protein synthesis to keep up their supply. rearrange the steps of protein synthesis into the correct order. place the first step at the top and the last step on the bottom. dna is unzipped in the nucleus. mrna moves to the cytoplasm. mrna encodes the message from the dna. a ribosome attaches to mrna. trna brings amino acids to the mrna. amino acids are linked to form a protein

Explanation:

Protein synthesis involves transcription and translation. First, DNA is unzipped in the nucleus to produce mRNA encoding the DNA - message (transcription). Then, mRNA moves to the cytoplasm. A ribosome attaches to mRNA, and tRNA brings amino - acids to the mRNA. Finally, amino acids are linked to form a protein (translation).

Answer:

1. DNA is unzipped in the nucleus
2. mRNA encodes the message from the DNA
3. mRNA moves to the cytoplasm
4. a ribosome attaches to mRNA
5. tRNA brings amino acids to the mRNA
6. amino acids are linked to form a protein
