- Q1a protein structure that divides the genetic material in a cell. These act like little lassos pulling the material apart.spindle fibers30s
- Q2disease in which certain cells divide uncontrollably.Cancer30s
- Q3the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells.cell cycle30s
- Q4the phase of the cell cycle in which a typical cell spends most of its life. During this phase, the cell copies its DNA in preparation for mitosis but is not actively dividing.Interphase30s
- Q5process by which a double-stranded DNA molecule is copied into two, identical DNA molecules.Replication30s
- Q6Tiny thread-like structures inside the nucleus made from DNA and protein, this information acts like a recipe that tells cells how to function.Chromosome30s
- Q7that part of the cell division process during which the cytoplasm of a single cell divides into two daughter cells.Cytokinesis30s
- Q8the first stage of cell division, before metaphase, during which the chromosomes become x-shaped as paired chromatids and the nuclear membrane disappears.Prophase30s
- Q9the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers and meet at the middle of the cell.Metaphase30s
- Q10the stage of cell division in which the chromosomes move away(like they are ripped apart) from one another to opposite poles of the cell.Anaphase30s
- Q11phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.Telophase30s
- Q12(in plant cells) a plate that develops at the midpoint between the two groups of chromosomes in a dividing cell forming the wall between the two new daughter cells.cell wall plate30s
- Q13the region of a chromosome to which the microtubules of spindle fibers the during cell division.Centromere30s
- Q14organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.Centriole30s
- Q15the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA. This appears as a very fine wad of strands.Chromatin30s
