CHAPTER 3 DNA
| Question | Answer |
|---|---|
| An individual’s entire set of DNA can be referred to as a | genome |
| The small water channels in the cell membrane are called: | aquaporins |
| During which stage of mitosis do the centrioles move to the opposite poles of the cell? | Prophase |
| The correct order of the phases of mitosis is: | prophase, metaphase, anaphase, telophase. |
| Water will move through the cell membrane by: | osmosis. |
| Which of the following terms is synonymous with tumor? | Neoplasm |
| Extensive weight training causes the muscle cells to: | hypertrophy. |
| The pairing of bases of a strand of DNA is obligatory. If a strand of DNA were composed of the base sequence of ATCG, what would be the obligatory sequence of its opposing base pairs? | TAGC |
| All of the following occur as a result of meiosis except: | chromosome number remains at 46. |
| All of the following are examples of passive transport except: | endocytosis |
| Which of the following is not true of RNA? | It contains deoxyribose sugar. |
| Phagocytosis is an example of: | endocytosis |
| A DNA molecule is characterized by all of the following except: | ribose sugar. |
| Diffusion requires: | a concentration gradient |
| Diffusion of particles through a membrane by means of a carrier molecule is called: | facilitated diffusion. |
| A membrane carrier structure attracts a solute to a binding site, changes shape, and releases the solute on the other side of the cell membrane. This describes the process of: | carrier-mediated transport. |
| Which is true about the sodium and potassium pump? | Three sodium ions are taken out of the cell. |
| When the chromosomes align themselves across the equator of the spindle fibers, it is characteristic of which phase of mitosis? | Metaphase |
| A saline solution that contains a higher concentration of salt than a red blood cell would be: | hypertonic |
| Transcription can be best described as the: | synthesis of mRNA. |
| A sequence of three bases forms a(n): | condon |
| Which of the following is not true of diffusion? | Uses cellular energy |
| NaCl would move through the cell membrane in which direction? | Both into and out of the cell |
| The physical process by which water and solute move through a membrane when a hydrostatic pressure gradient exists across the membrane is the process of: | filtration |
| Which of the following statements is true? | The site of transcription is within the nucleus, whereas the site of translation is in the cytoplasm. |
| Two solutions of different concentrations of glucose are separated by a membrane that allows both glucose and water to pass through. When dynamic equilibrium is reached, there will be: | an even exchange of material across the membrane. |
| Twenty-three chromosomes per cell in humans is referred to as: | haploid |
| If a sequence of nitrogen bases in nucleic acid were A-U-C-G-A, which of the following would be true about the nucleic acid? | It contains ribose sugar. |
| Which is not true about the sodium and potassium pump? | Sodium moves into the cell and potassium moves out of the cell. |
| Materials can be moved from a low concentration to a high concentration through: | active transport. |
