What are the monomers of proteins called?

• Nucleotides

• Amino acids

• Peptide bonds

• Enzymes

What is the role of enzymes in chemical reactions?

• They provide energy for the reactions

• They act as a catalyst that influences the rate of the reactions

• They store genetic information for the reactions

• They prevent the reactions from occurring

• Adenine, Guanine, Uracil, Cytosine

• Adenine, Guanine, Thymine, Cytosine

• Adenine, Guanine, Thymine, Uracil

During DNA replication, what is the role of DNA polymerase?

• It separates the DNA strands.

• It reads the DNA template and adds complementary base pairs.

• It creates hydrogen bonds between nitrogenous bases.

• It coils the DNA into a double helix.

What must happen before DNA replication can occur?

• The DNA must replicate autonomously without any changes.

• The hydrogen bonds between nitrogenous bases must be strengthened.

• The hydrogen bonds that hold the nitrogenous bases together must be broken.

• The DNA must form a triple helix.

Where does transcription, the process by which mRNA is made from DNA, occur?

• Cytoplasm

• Ribosome

• Nucleus

• Mitochondria

What is the correct order of molecules involved in protein synthesis?
