Cell Cycle
Chromosome Separation
Cell Division
Chromosome Duplication
Eukaryotes
Linear Chromosome
Prokaryotes
Circular Chromosome
Genetic Information Transmition
Asexual Reproduction
Unequal Division
budding
single daughter cell forms as bud of parent cell
Equal Division
binary fission
the parent divides into two equal daughter cells
Mitosis
Metaphase
spindle fibers attach to centromere of each sister chromatid
Anaphase
sister chromatids pulled apart shortening spindle fibers
Prophase
chromosomes condense, tight structures, envelope breaks down, spindle starts to form
Telophase
chromosomes begin to uncoil form chromatin, spindle breaks down, new envelope form
Cytokinesis
cytoplasm splits in two and cell divides
Interphase
S
chromsomes duplicated
G1
protein synthesis
G2
cell prepares to enter mitosis
