Chapter 10 Flashcards
Cell Division
Process by which a cell divides into two new daughter cells
Asexual Reproduction
Process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
Sexual Reproduction
Fusion of two parent cells.
Chromosomes
Threadlike structures of DNA and protein that contain genetic information; in eukaryotes, chromosomes are found in the nucleus, in prokaryotes, they are found in the cytoplasm
Chromatin
Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
Cell Cycle
Series of events in which a cell grows, prepares for division, and divides to form two daughter cells
Interphase
“Inbetween period of growth”
Cytokinesis
Division of the cytoplasm to form two separate daughter cells
Chromatid
One of the two identical “sister” parts of a duplicated chromosome
Prophase
first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become viable
Centromere
region of the chromosome where the two sister chromatids attach
Centrioles
structure in an animal cell that helps to organize cell division
Metaphase
phase in mitosis in which the chromosomes line up across the center of the cell
Anaphase
Phase in mitosis in which the chromosomes separate and move to opposite ends of the cell
Telophase
Final phase, chromosomes spread out snd dangle in chromatin
