Question Answer
DNA A chemical that contains information for an organism's growth and functions. Genetic Material
Cell Cycle All the changes the cell goes through from one cell division to the next. Mitosis, Interphase, Prophase, Metaphase, Anaphase, Telophase.
Chromosomes DNA is wrapped around protiens like thread arouond a spool and compacted into structures.
Chromatids One of two identical chromosomal strands into which a chromosome splits longitudinally preparaty to cell division.
Mitosis The part of the cell cycle during which the nucleus divides.
Interphase The part of the cell cycle during which a cell is not dividing.
Double Helix The shape of the DNA.
Cytokinesis The division of the parent cell's cytoplasm.
Centromere 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.
Binary Fission The form of asexual reproduction occurring in prokaryotes.
Regeneration The process of new tissue growth at these sites. A starfish gets its arms cut off it can grow them back.
Asexual Reproduction One organism produces one or more new organisms that are identical to itself and that live independently of it. One parent has one or more organisms that are exactly like it.
Sexual Reproduction A type of reproduction in which male and female reproductive cells combine to form offspring with genetic material from both cells.
Prophase 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.
Metaphase The third stage of cell division, during which chromosomes line up in preparation for separation.
Anaphase The fourth stage of cell divison where the chromosomes get pulled apart by the fibers.
Telophase The last stage of mitosis where there are two cells conected and are pinching together then divide.
Centrioles In an animal cell, a two-part rod-shaped structure with the parts lying at right angles to each other, located in pairs near the nucleus. Important part of cell division.
Budding A form of asexual reproduction in which an outgrowth of the parent becomes constricted and eventually separates to form a new individual.
