Nitrogenous bases are joined by which type of bond?

• polar bonds
• ionic bonds
• covalent bonds
• hydrogen bonds

Which of the following is the blueprint for the production of RNA within a cell?

• DNA
• protein
• ATO
• carbohydrate

When an extra base is inserted into the DNA sequence of a gene, the protein doesn't work. Which explains why?

• the base increases rate of translation
• the base causes DNA to be transcribed in opposite direction
• the inserted base causes the codons in the sequence to be incorrect for the desired protein
• the base signals enzymes to translate DNA rather than RNA

What is the relationship between a protein, the cell, and DNA?

• DNA is produced by protein which is produced in the cell
• Protein is composed of DNA which is produced in the cell
• DNA controls the production of protein in the cell
• A cell is composed of DNA and protein
