Practice for Oct 11 & 12th

a protein structure that divides the genetic material in a cell. These act like little lassos pulling the material apart.

disease in which certain cells divide uncontrollably.

the 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.

the 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.

process by which a double-stranded DNA molecule is copied into two, identical DNA molecules.

Tiny thread-like structures inside the nucleus made from DNA and protein, this information acts like a recipe that tells cells how to function.

that part of the cell division process during which the cytoplasm of a single cell divides into two daughter cells.

the first stage of cell division, before metaphase, during which the chromosomes become x-shaped as paired chromatids and the nuclear membrane disappears.

the 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.

the stage of cell division in which the chromosomes move away(like they are ripped apart) from one another to opposite poles of the cell.

phase 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.

(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.

the region of a chromosome to which the microtubules of spindle fibers the during cell division.

organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.

the 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.
