Biology - Chapter 11.2 Vocabulary

Define cytokinesis

• series of events in which a cell grows, prepares for division, and divides to form two daughter cells

• part of eukaryotic cell division during which the cell nucleus divides

• division of the cytoplasm to form two separate daughter cells

• A nuclear envelope that forms around the cluster of chromosomes

Define Chromatid

• threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next

• substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones

• Your uncle’s left tibia

• one of two identical “sister” parts of a duplicated chromosome

Define interphase

• the phase in which the chromosomes intertwine

• Period of the cell cycle between cell divisions in which the cell grows

• Plants do not have centrioles but they organize spindles directly from their centrosome regions.

• Biologists think of this cycle as first cell division, and interphase (period of cell growth) and repeat.
