Question

students learn that cells manufacture proteins using dna as the blueprint. they wonder about the protein synthesis process. how do cells use dna to produce proteins? place the steps below in order.
1.
2.
3.
4.
5.
a complementary strand of mrna is formed.
a portion of the dna double helix is unwound.
mrna bonds with a ribosome in the cytoplasm.
a chain of amino acids is made by trna molecules.
secondary and tertiary structures are formed by folding.

Explanation:

Protein synthesis starts with DNA unwinding. Then mRNA is formed as a complementary strand. mRNA moves to the cytoplasm and bonds with a ribosome. tRNA molecules assemble amino - acids into a chain. Finally, folding creates secondary and tertiary structures.

Answer:

1. A portion of the DNA double helix is unwound.
2. A complementary strand of mRNA is formed.
3. mRNA bonds with a ribosome in the cytoplasm.
4. A chain of amino acids is made by tRNA molecules.
5. Secondary and tertiary structures are formed by folding.
