1. How does the sequence of a strand of DNA correspond to the amino acid sequence of a protein ? This concept is explained by the central dogma of molecular biology which states that :   DNA is replicated and sections of the replica are used to make protein.   DNA is used to make RNA which is used to make protein.   protein is manufactured directly from DNA without any intermediate.   None of the above.   Hint Half-n-half Clue   2. The total length of a DNA molecule in the human genome when fully outstretched is approximately :   1.8 centimeters.   1.8 meters.   Varies from person to person.   1.8 millimeters.   Half-n-half Clue   3. A significant difference between prokaryotes and eukaryotes is :   Prokaryote cells are not membrane-bound while eukaryote cells are.   Prokaryotes do not have ribosomes while eukaryotes do.   Prokaryotes do not have DNA as their genetic material while eukaryotes do.   The DNA of prokaryotes floats freely around the cell while the DNA of eukaryotes is held within its nucleus.   Half-n-half Clue   4. A nucleoside consists of :   a pentose sugar and a nitrogeneous heterocyclic base.   a hexose sugar and a nitrogeneous heterocyclic base.   a phosphate group, a pentose sugar and a nitrogeneous heterocyclic base.   a pentose sugar and a oxygen base.   Half-n-half Clue   5. Where would you expect to find genetic information describing the characteristics of a Dodo ?   In its feathers !   In virtually every cell in its body.   In the primary spermatocytes.   In the ribosomes.   Half-n-half Clue   6. A DNA strand has the sequence A-C-A-G-C-C-G-T-A. What would be its complementary strand ?   A-C-A-G-C-C-G-T-A   G-T-G-A-T-T-A-C-G   T-G-T-C-G-G-C-A-T   U-G-U-C-G-G-C-A-U   Half-n-half Clue   7. The number of hydrogen bonds that hold the Adenine - Thymine base pair together is :   4   5   3   2   Half-n-half Clue
