Chapter 6 Crossword Puzzle

Across
the period of the cell cycle when duplicated chromosomes are distributed into two nuclei and the cytoplasmic contents are divided; includes mitosis and cytokinesis
a mutated version of a proto-oncogene, which allows for uncontrolled progression of the cell cycle, or uncontrolled cell reproduction
the equatorial plane midway between two poles of a cell where the chromosomes align during metaphase
the position of a gene on a chromosome
the region of the prokaryotic chromosome at which replication begins
the entire genetic complement (DNA) of an organism
mechanisms that monitor the preparedness of a eukaryotic cell to advance through the various cell cycle stages
the second, or synthesis phase, of interphase during which DNA replication occurs
a protein structure in the centromere of each sister chromatid that attracts and binds spindle microtubules during prometaphase
the period of the cell cycle at which the duplicated chromosomes are separated into identical nuclei; includes prophase, prometaphase, metaphase, anaphase, and telophase
the stage of mitosis during which sister chromatids are separated from each other
a constriction formed by the actin ring during animal-cell cytokinesis that leads to cytoplasmic division
describes a cell, nucleus, or organism containing one set of chromosomes (n)
a structure formed during plant-cell cytokinesis by Golgi vesicles fusing at the metaphase plate; will ultimately lead to formation of a cell wall to separate the two daughter cells
Down
the microtubule apparatus that orchestrates the movement of chromosomes during mitosis
a haploid reproductive cell or sex cell (sperm or egg)
chromosomes of the same length with genes in the same location; diploid organisms have pairs of homologous chromosomes, and the members of each pair come from different parents
the stage of mitosis during which chromosomes are lined up at the metaphase plate
the division of the cytoplasm following mitosis to form two daughter cells
the stage of mitosis during which mitotic spindle fibers attach to kinetochores
the period of the cell cycle leading up to mitosis; includes G1, S, and G2 phases; the interim between two consecutive cell divisions
the process of prokaryotic cell division
describes a cell, nucleus, or organism containing two sets of chromosomes (2n)
describes a cell that is performing normal cell functions and has not initiated preparations for cell division
the ordered sequence of events that a cell passes through between one cell division and the next
a paired rod-like structure constructed of microtubules at the center of each animal cell centrosome
the physical and functional unit of heredity; a sequence of DNA that codes for a specific peptide or RNA molecule
