DNA
A complex molecule containing the genetic information that makes up the chromosomes.
Chromosomes
threadlike structures made of DNA molecules that contain the genes
daughter cells
new cells produced by cell division
Mitosis
Cell division of body cells
regneration
regrowth of a lost or injured part; replacement of cells by mitosis; hydra, starfish, salamanders, tadpoles
asexual reproduction
A reproductive process that involves only one parent and produces offspring that are identical to the parent.
Budding
A form of asexual reproduction of yeast in which a new cell grows out of the body of a parent.
binary fission
A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
Sporulation
Seed like structures holds dna and releases it when ever it lands to grow an identical organism
Stages of Mitosis
prophase, metaphase, anaphase, telophase
Interphase
Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases
Prophase
Chromosomes become visable, nuclear envelop dissolves, spindle forms
Metaphase
second phase of mitosis, during which the chromosomes line up across the center of the cell
Anaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
Telophase
the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
one half of a chromosome
chromatid
What holds chromosomes together?
centromere
Where does the cell spend the most time?
Interphase
