DNA & Protein Synthesis

Which of the following best describes a DNA molecule?

• double helix
• contains ribose
• made of amino acids
• contains Uracil

Which of the following units are repeatedly joined together to form a strand of DNA?

• amino acids
• nucleotides
• fatty acids
• polysaccharides

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of

• cytosine
• guanine
• thymine
• uracil

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

Where does Translation take place?

• RNA
• ribosome
• nucleus
• chromosome

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

Which shows the correct complementary base pairing for DNA?

• C-A, T-G
• A-G, C-T
• C-G, U-A
• T-A, G-C

DNA codes for...

• cholesterol
• proteins
• fatty acids
• a sandwich

The DNA sequence TACGAA would be transcribed to

• AUGCUU
• ATGCTT
• GCATCC
• GCAUCC

Translation is important because it __________.

• Converts mRNA into a polypeptide
• Replicates the genetic information in DNA
• Produces RNA from DNA molecules
• Recycles tRNA molecules for reuse
