| Question | Answer |
|---|---|
| DNA replicates during interphase. | false |
| Which of the following types of cells produce gametes? | germs |
| Four of the five answers listed below are events occurring during mitosis. Select the exception. (chromosome (DNA) replication) division of centromere lining chromosomes up at the cellular equator spindle microtubules attach to centromeres chromosomes migrate to opposite ends of the cell | (exam answer= chromosome (DNA) replication ) division of centromere lining chromosomes up at the cellular equator spindle microtubules attach to centromeres chromosomes migrate to opposite ends of the cell |
| Which of the following is the proper sequence for mitosis? | Prophase, Metaphase, Anaphase, and Telophase.(PMAT) |
| Chromatids that are attached at the centromere are called what kind of chromatids? | sister |
| Which of the following reproduce by prokaryotic fission? | bateria |
| The daughter cells produced by mitosis are called gametes. | false |
| Meiosis occurs in body cells. | false |
| How many times does DNA loop around the histone proteins in a nucleosome? | two |
| DNA replication occurs | between the gap phases of interphase. |
| The spindle apparatus consists of | microtubules |
| Mitosis | is the period of nuclear division? |
| Proteins associated with DNA in eukaryotes are | histones |
| The distribution of cytoplasm to daughter cells is accomplished during | cytokinesis (cytoplasmic division). |
| During this stage of the mitotic cell cycle the chromosomes are lined up on the equatorial plate. | metaphase |
| The diploid chromosomes number is also referred to as | 2N |
| Dynein and kinesin are _____________ proteins in a kinetochore. | motor |
| The spindle, or spindle apparatus, becomes visible during | prophase |
| Four of the five answers listed below assist in chromosome movement. Select the exception. microtubule spindle microtubules centromeres centriole nuclear envelope | nuclear envelope |
| In mitosis, if a parent cell has 16 chromosomes, each daughter cell will have how many chromosomes? | 16 |
| New daughter nuclear membranes form during this phase. | Telophase |
| Chromosomes replicate during this phase of the mitotic cell cycle. | interphase |
| Mitosis comes from the Greek word mitos, which means | thread |
| The (replicated) chromosomes detach from one another and become visibly separated during | anaphase |
| The nuclear membrane reforms during | telophase |
| Which is the period that is commonly followed by cytokinesis? | mitosis |
| The two sets of genetic information in a cell are described by the term | diploid |
| During which period is DNA duplicated? | S |
| As mitosis ends, vesicles move to the equator. vesicle membranes fuse. materials in vesicle are sandwiched between the two membranes. cellulose is deposited and the cell plate grows. | all of the above occur. |
| The period when interphase ends in the parent cell is | gap 2 |
| In plant cells, cytokinesis occurs with the formation of a | cell plate |
| The chromosomes are aligned at the spindle equator during | metaphase |
| Which is the event that forms two daughter cells? | cytokinesis |
| The chromosome number in the daughter cells is twice the chromosome number of the parent cell. | false |
| Which of the following is not an actual phase of mitosis? | interphase |
| Another name for body cells is _______ cells. | somatic |
| The chromosomes and genes are actually replicated during | interphase |
| Which of the following is the nuclear division mechanism that produces gametes? | meiosis |
| Which is the period in which metaphase occurs? | mitosis |
| When a cell undergoes mitosis the daughter cells have identical genes. the daughter cell has genes identical to those of the mother cell that produced it. the amount of cytoplasm in the mother cell and in each of the daughter cells is equal. both a and b are true. | A) the daughter cell has genes identical to those of the mother cell that produced it. B) the amount of cytoplasm in the mother cell and in each of the daughter cells is equal. (exam answer both a and b are true.) |
| Condensation and shortening of chromosomes occur during this phase. | prophase |
| In which of the stages below does the chromosome consist of two DNA molecules (sister chromatids)? | metaphase and prophase |
| The small, disk-shaped structure on the surface of the centromere that serves as docking sites for spindle microtubules is the __________. | kinetochore |
| If the diploid chromosome number is 16, the chromosome number of each gamete will be | 8 |
| Histone-DNA units are called | nucleosomes |
| HeLa cells are the cultured descendants of cells isolated from a(n) | cancer cells |
| If the total number of chromosomes in a cell is 6, then after mitosis there will be | 6 chromosomes in each daughter cell |
| During this phase the centromeres break apart as the separated sister chromatids begin to move to opposite poles. | anaphase |
| Daughter cells produced by mitosis are genetically identical to the parent cell. | true |
| Which is the period of cell growth before DNA duplication? | Gap 1 |
