Science Crossword

a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells
the cycle of growth and asexual reproduction of a cell
Uncontrollable growth and multiplication of cells
Programmed cell death
First stage of cell division in which the cell undergoes growth (the cell is in this phase about 90% of its life)
the chromatin condenses into discrete chromosomes. The nuclear envelope breaks down and spindles form at opposite poles of the cell(1st phase of mitosis)
the chromatin condenses into discrete chromosomes. The nuclear envelope breaks down and spindles form at opposite poles of the cell (2nd phase of mitosis)
the paired chromosomes (sister chromatids) separate and begin moving to opposite ends (poles) of the cell. Spindle fibers not connected to chromatids lengthen and elongate the cell (3rd phase of mitosis)
the chromosomes are cordoned off into distinct new nuclei in the emerging daughter cells (4th phase of mitosis)
the division of the cell's cytoplasm, It begins prior to the end of mitosis in anaphase and completes shortly after telophase/mitosis. At the end two genetically identical daughter cells are produced. These are diploid cells, with each cell containing a full complement of chromosomes.
Unzips DNA to prepare for DNA replication.
A protein that binds to cyclin-dependent kinases.
Structures that contain identical copies of DNA
Structure at the center where chromatids attach
Condensed structures that contain the DNA that are visable during mitosis.
A structure containing spindle fibers, aster fibers, and centrioles.
Substances or agents known to cause cancer.
enzymes that create DNA molecules by assembling nucleotides
reproduce by mitosis making daughter cells that are exact replicas.
a result of the process of meiosis, a type of cell division in which diploid cells divide to give rise to haploid germ cells
