As in most areas of biology, the study of mitosis and the cell cycle involves a lot of new terminology. Knowing what the different terms mean is essential to understanding and describing the processes occurring in the cell. Drag the terms on the left to correctly complete these sentences. Not all the terms will be used. View Available Hint(s) Reset Help 1. DNA replication produces two identical DNA molecules, called | sister chromatid(s) . which separate during mitosis. 2. After chromosomes condense, the centrosome(s) is the region where the identical DNA molecules are most tightly attached to each other 3. During mitosis, microtubules attach to chromosomes at the kinetochore(s) 4. In dividing cells, most of the cell’s growth occurs during interphase S. The mitotic spindle(s) is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division 6. During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called chromatin 7. In most eukaryotes, division of the nucleus is followed by cytokinesis, when the rest of the cell divides. 8. The centromere(s)are the organizing centers for microtubules involved in separating chromosomes during mitosis Can you recognize the eight stages of meiosis based on the location and behavior of the chromosomes? Drag the diagrams of the stages of meiosis onto the targets so that the four stages of meiosis I and the four stages of meiosis II are in the proper sequence from left to right. (Note that only one of the two daughter cells is shown for meiosis lI.) View Available Hint(s) Reset Help Meiosis Meipsis I Drag the name of the appropriate stage of meiosis to the target above each diagram. Then, in the pink target below each diagram, specify whether the configuration of the chromosomes related to crossing over is possible or impossible/unlikely.
