Question

Match each description of a structure with the proper number of structural components it has. The number of centrosomes present during interphase The number of centrosomes present during metaphase The number of kinetochores on each chromosome during mitotic prometaphase The number of microtubules in a mitotic spindle Match each description with the proper motor protein it would be associated with. Movement of vesicles from the Golgi to the plasma membrane. Movement of forming Golgi vesicles to the center of the cell. Movement of secretory vesicles to the end of an axon Movement of recycled waste products from the end of an axon back to the cell body by the nucleus Movement of a vesicle towards one of the two centrosomes during mitosis. Movement of a thick filament along an actin thin filament Movement of membrane components up to the tip of a eukaryotic flagella Movement of material from the tip of a flagella back towards the cell Match each description with its proper mitotic stage The nuclear envelope is broken down but many of the chromosomes are not fully attached to the spindle microtubules The new cell plate in a plant cell is beginning to form along with new nuclei The nuclear envelope is still intact but the chromosomes have condensed The kinetochores from both sister chromatids have attached to microtubules from opposite poles, but the sister chromatids are still attached and aligned midway between the poles What mitotic stage is this cell in? [based on a picture shown on the quiz]

Explanation / Answer

9. The number of centrosomes present during interphase - 2

The number of centrosomes present during metaphase - 1 in each cell

The number of kinetochores on each chromosome during mitotic prometaphase - 2

The number of microtubules in a mitotic spindle - 2

11. The nuclear envelope is broken down but many of the chromosomes are not fully attached to the spindle microtubules - Prometaphase

The new cell plate in a plant cell is beginning to form along with new nuclei - Telophase

The nuclear envelope is still intact but the chromosomes have condensed - Prophase

The kinectochores from both sister chromatids have attached to microtubules from opposite poles, but the sister chromatids are still attached and aligned midway between the poles - Metaphase.
