Term
Chromosomes-
Definition
Coiled up DNA that looks like an X.
Term
Chromatid-
Definition
Half of a chromosome.
Term
Centromere-
Definition
A round structure that holds two chromatids together = making a chromosome.
Term
Binary Fission-
Definition
The division of Prokaryotic cells.
Term
Mitosis-
Definition
Division of eukaryotic cells.
Term
Prophase-
Definition
DNA coils up and the chromosomes become visible.
Term
Spindle-
Definition
Fibers that connect to the centrioles and centromeres.(The fibers move the chromosomes around.)
Term
Metaphase-
Definition
The spindle fibers line the chromosomes up in the middle of the cell.
Term
Anaphase-
Definition
Centromeres divide turning the diploid chromosomes into haploid chromatids.(The spindle fibers move the chromatids to opposite ends of the cell.)
Term
Telophase-
Definition
The nuclear membranes reappear and cytokinesis occurs.(The cell completely splits into 2 identical daughter cells)
Term
Interohase-
Definition
The time of a cells life when it is not undergoing.
Term
G1 phase-
Definition
First growth phase the cell grows rapidly and performs routine functions.
Term
S phase-
Definition
Synthesis phase DNA copies itself.
Term
G2 phase-
Definition
Second growth phase the nucleus prepares for mitosis and other organelles make copies of themselves.
Term
M phase-
Definition
Mitosis.
