What holds the nucleotides together in DNA? a. Phosphate group b. Hydrogen bonds c. Sugar d. Base 8. The "backbone" of a DNA molecule refers to a. Its vertebral spine b. Nucleotide base parings: A and T, G and C c. Hydrogen bonds d. Chain of sugar-phosphate 9. Why is the name "double-helix" used to describe a DNA molecule? a. Because it contains two parings of nucleotides. b. Because the two chains of nucleotides that run antiparallel to each other twist and form a helical shape. c. Because it contains more than one hydrogen bond per nucleotide pairing. d. Because the two chains of nucleotides lack hydrogen bonds that they become susceptible to bending. 10. Which enzyme is responsible for adding new nucleotides to the newly synthesized DNA strand? a. DNA polymerase b. RNA primase c. RNA polymerase d. Helicase 11. Which of the following statements is false about DNA and RNA? a. DNA contains the nucleotide thymine while RNA uses the nucleotide uracil. b. Both DNA and RNA contain a sugar and phosphate backbone. c. DNA contains an extra oxygen atom on the sugar while RNA is missing that atom. 12. What is the important factor in the instructions of a gene that determine which amino acid to use to build proteins? a. The type of RNA molecule that is used to make the protein b. The order of the nucleotides in DNA c. Whether if transcription or translation is used in the process to build a protein d. If there is an enzyme present to catalyze the process
Several different nucleic acids are involved in the process of getting a protein produced from a gene. DNA contains the “genetic code” for the protein. DNA is double-stranded, but only one strand is transcribed into mRNA. The mRNA then goes into the cytoplasm where it is translated into protein with the help of tRNA. At each stage of the process, there is base complementarity (A pairs with T/U and C pairs with G) between the nucleic acids involved to ensure the integrity of the DNA blueprint for the protein being produced. Therefore, some of the four strands of nucleic acids involved will match (except U replaces T in RNA) and some will have base complementarity. Indicate whether there is matching (1) or base complementarity (2) between the following nucleic acids.
