DNA/RNA/Protein Synthesis Concept 2

Which pair of nucleotides are held together by hydrogen bonds?

• A and U
• A and G
• G and C
• U and G

What structure in a cell is the site for making proteins?

• ribosomes
• mitochondria
• lysosome
• Golgi body

When amino acids are bonded together, what kind of molecule do they make?

• nucleic acid
• polysaccharide
• lipid
• protein

Which base is normally used in the synthesis of RNA but not in DNA?

• adenine
• uracil
• cytosine
• guanine

With respect to normal base pairing, when a molecule of DNA replicates, thymine will pair with

• adenine
• cytosine
• guanine
• uracil

Where in a DNA molecule would you find the hydrogen bonds?

• Between the phosphate and sugar
• Between the sugar and nitrogen bases
• Between the nitrogen bases
• At the phosphates

Specific proteins produced in a cell are directly related to the 

• number of mitochondria in the cell
• types of ribosomes in the cell
• sequence of sugars and phosphates in the cell
• sequence of nucleotides in the DNA
