Question

label the steps for protein synthesis in order, beginning with the first step.
once the protein is made, the gene for a particular trait is expressed.
mrna joins the ribosome, and the anticodons from trna join mrna to form a chain of amino acids.
an enzyme unzips dna and free rna nucleotides join dna to form mrna.
a chain of amino acids is formed from peptide bonds, creating a protein.
mrna is transported from the nucleus of the cell to the ribosomes of the cell.

Explanation:

Protein synthesis has two main phases: transcription (in the nucleus) and translation (at ribosomes). First, DNA is transcribed to mRNA. Then mRNA moves to ribosomes, where tRNA assembles amino acids into a chain, which folds into a protein, finally expressing the gene.

Answer:

1. an enzyme unzips DNA and free RNA nucleotides join DNA to form mRNA.
2. mRNA is transported from the nucleus of the cell to the ribosomes of the cell.
3. mRNA joins the ribosome, and the anticodons from tRNA join mRNA to form a chain of amino acids.
4. A chain of amino acids is formed from peptide bonds, creating a protein.
5. Once the protein is made, the gene for a particular trait is expressed.
