Science Flashcards
Magnification
The ability of lenses to enlarge the image of specimen
DNA
A cells genetic info
DNA is organized into chromosomes
The Cell Cycle
The majority of a cells life is spent growing and repairing
Cells divide before they get too big
Interphase
Cell is growing and preparing for division
Mitosis
The packaging of the genetic material in the nucleus into two equal portions
Cytokinesis
The separation of the cytoplasm into two equal portions
(Daughter cells)
Prophase
Chromosomes condense and thicken
Nuclear membrane dissolves
Metaphase
Chromosomes line up at the cell equator
Anaphase
Chromosomes separate and are pulled to opposite poles
Telophase
Nuclear membranes form around each group of chromosomes to form two new nuclei
Cytokinesis
The cytoplasm and organelles are divided amount the two new cells
Cancer occurs
Mutations occur in the gene that control cell division
Abnormally grown cells interfere and disrupt other cell functions, and take in other cells nutrients
