1. A DNA strand has the sequence A-C-A-G-C-C-G-T-A. What would be its complementary strand ?   U-G-U-C-G-G-C-A-U   A-C-A-G-C-C-G-T-A   T-G-T-C-G-G-C-A-T   G-T-G-A-T-T-A-C-G   Hint Half-n-half Clue   2. The total length of a DNA molecule in the human genome when fully outstretched is approximately :   1.8 millimeters.   1.8 centimeters.   1.8 meters.   Varies from person to person.   Half-n-half Clue   3. Because one original strand of the double stranded DNA helix is found in each daughter cell (after cell division), the DNA replication process is :   semiconservative   derivative   conservative   dispersive   Half-n-half Clue   4. The technique Rosalind Franklin used to determine the structure of DNA was :   centrifuge analysis   X-Ray crystallography   bacteriophages   None of the above   Half-n-half Clue   5. A significant difference between prokaryotes and eukaryotes is :   Prokaryotes do not have DNA as their genetic material while eukaryotes do.   Prokaryote cells are not membrane-bound while eukaryote cells are.   The DNA of prokaryotes floats freely around the cell while the DNA of eukaryotes is held within its nucleus.   Prokaryotes do not have ribosomes while eukaryotes do.   Half-n-half Clue   6. The unit within the nucleus that contains a protein complex (located at the center of the unit) of two H2A, H2B, H3 and H4 histone proteins with DNA wrapped around the complex in two turns, each turn consisting of about 80 base pairs is called a :   centrosome   ribosome   nucleosome   histosome   Half-n-half Clue   7. The DNA molecules of different species differ in their :   phosphate backbone   sequence of bases   type of nucleotides   All of the above   Half-n-half Clue
