1. A nucleoside consists of :   a pentose sugar and a oxygen base.   a phosphate group, a pentose sugar and a nitrogeneous heterocyclic base.   a hexose sugar and a nitrogeneous heterocyclic base.   a pentose sugar and a nitrogeneous heterocyclic base.   Hint Half-n-half Clue   2. The process of protein manufacture within ribosomes using mRNA is called :   transcription   protein derivation   translation   None of the above   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 :   derivative   conservative   dispersive   semiconservative   Half-n-half Clue   4. The DNA molecule is a polymer. Its monomer units are :   nucleotides   nucleosides   amino acids   nucleic acids   Half-n-half Clue   5. A significant difference between prokaryotes and eukaryotes is :   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.   Prokaryotes do not have DNA as their genetic material while eukaryotes do.   Prokaryote cells are not membrane-bound while eukaryote cells are.   Half-n-half Clue   6. 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   7. 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   U-G-U-C-G-G-C-A-U   T-G-T-C-G-G-C-A-T   Half-n-half Clue
