  1. The Central Dogma refers to the flow of inherited information from:
    DNA to RNA to protein
  2. If a DNA molecule has 40% thymine, then is DNA also contains:
    40% adenine and 10% cytosine
  3. A nucleotide is:
    a five-carbon sugar, a phosphate group and a nitrogen-containing base
  4. RNA differs from DNA in that only RNA contains:
    the base uracil and has a sugar ribose
  5. The bond connecting the sugar of one nucleotide with the phospate of a second nucleotide along the DNA sugar-phosphate backbone is called a:
    phosphodiester bond
  6. The bonds between the complementary base pairs in the DNA  helix are:
    hydrogen bonds
  7. Polymerases synthesize nucleic acids only in the:
    5' to 3' direction
  8. The information on how to make proteins is carried to the DNA in a code specified by the:
    sequence of nucleotide bases
  9. Because the synthesis of DNA consists of 1/2 originial DNA strand and 1/2 new DNA, DNA replication is said to be:
    semiconservative
  10. DNA strands are said to be _______ because one strand runs in the 5' to 3' direction and the opposite strand runs in the 3' to 5' direction
    antiparallel
  11. In DNA synthesis, the enzyme that erases the primer and fills the gap with DNA is called:
    DNA polymerase I
  12. During the process of transcription, the information in:
    DNA is converted into RNA information
  13. Which action does RNA polymerase differ from DNA polymerase?
    RNA polymerase uses RNA as a template, and DNA polymerase uses a DNA template
  14. A biochemist is studying the process of how a protein chain is assembled. Which cellular structure would he or she be studying?
    Ribosomes
  15. Each amino acid is attached to the growing polypeptide chain by a(n)
    peptide bond
  16. Transcription of part of a DNA molecule with a nucleotide sequence of A-A-A-C-A-A-C-T-T results in a mRNA molecule with the complementary sequence of:
    U-U-U-G-U-U-G-A-A
  17. The function of tRNA is to:
    transport amino acids to the ribosome
  18. Two daughter cells are most likely to inherit which of the following from the parent cell? A change in a_____
    Nucleotide in DNA
  19. If you knew the sequence of nucleotides within a gene, which one of the following could you determine with the most accuracy
    The primary structure for the protein
  20. The _______ of a tRNA molecule will attract the codon of an mRNA molecule.
    Anticodon
  21. During translation, elongation continues until _______ appears in the A site
    a stop codon
