DNA & Protein Synthesis

What kind of biomolecule is the DNA?

• Protein

• Carbohydrate

• Lipid

• Nucleic Acid

Why is the hydrogen bond important in the DNA molecule?

• It joins two sugars together

• It stabilizes the DNA structure and allows replication to happen

• It joins 2 amino acids to form proteins

• It creates ATP for protein synthesis

Which statement is TRUE about the DNA?

• It is a single helix

• In a DNA molecule, A pairs with U, and C pairs with G

• It contains the instructions in making proteins

• It builds and repair tissues

What is the role of DNA in protein synthesis?

• It determines the sequence of amino acids in a protein

• It goes out out of the nucleus to carry the message to the ribosome

• It transfers the amino acid to the ribosome

• It creates ATP
