Chapter 3

Question Answer
The physical struture in a cell that contains the cell's genetic material. chromosome
The genetic material found in all living cells that contains the information needed for an organism to grow, maintain its self and reproduce Deoxyribonucleic acid. and it looks like a twisted ladder DNA
one of two identical chromosomal strands into which a chromosome splits chromatids
The normal sequence of growth,maintenance, and division in a cell. cell cycle
The phase in the cell cycle during which mitosis
the period of the cell cycle during which the nucleus is not undergoing division interphase
the spiral arrangement of the two complementary strands of DNA. double helix
the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus. cytokinesis
a specialized structure on the chromosome, appearing during cell division as the constricted central region where the two chromatids are held together and form an X shape. centromere
fission into two organisms approximately equal in size. binary fission
the restoration or new growth by an organism of organs, tissues, etc., that have been lost, removed, or injured. regeneration
reproduction, as budding, fission, or spore formation, not involving the union of gametes. asexual reproduction
reproduction involving the union of gametes. sexual reprodution
the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. prophase
the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle. metaphase
the stage in mitosis or meiosis following metaphase in which the daughter chromosomes move away from each other to opposite ends of the cell. anaphase
the final stage of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes. telophase
a small, cylindrical cell organelle, seen near the nucleus in the cytoplasm of most eukaryotic cells, that divides in perpendicular fashion during mitosis, the new pair of centrioles moving ahead of the spindle to opposite poles of the cell as the cell di centrioles
a small, rounded outgrowth produced from a fungus spore or cell by a process of asexual reproduction, eventually separating from the parent cell as a new individual: commonly produced by yeast and a few other fungi. budding
