  • Back
gametes
reproductive cells
somatic
all other non-reproductive cells in the body
mitosis
a division of genetic material that produces daughter cells that are genetically identical to their parent cell
-IPPMAT
cytokinesis
usually accompanies mitosis, and divides cytoplasm into two daughter cells
-animals - cleavage furrow
-plants - cell plate
Three key events of mitosis and cytokinesis
1)Growth
2)Wound repair
3)Reproduciton (asexual)
chromosome
made up of a single long DNA strang wrapped around protein in a highly complex manner
cell cycle
-orderly sequence of events that occcurs from teh formation of a eukaryotic cell, through the duplication of its chromosomes, to the time it undergoes division itself.
-two key events:
1)replication of genetic material (S)
2)partitioning of copied chromosomes into daughet cells (M)
-also G2 to perform all other necessary functions (organelle replication, cytoplasm production and G1 other regular cell functions
chromatid
-each of the DNA copies in a replicated chromosome
-from the same chromosome = sister chromatids
centromere
specialized region where chromatids are joined
chromatin
complex of DNA and protein (histones) that compose eukaryotic chromosomes
centrosome
made up of two centrioles- center for microtubule-organizing center for mitotic spindle
Interphase
-DNA replicated (S)
-Organelles, cytoplasm replicated
-centrosomes replicated
Prophase
-Chromosomes condense
-mitotic spindle begins to form
Prometaphase
-Nuclear envelope breaks down
-spindle fibers connect with kinetochore
Metaphase
-chromosomes complete migration to the middle of the cell (metaphase plate)
Anaphase
-sister chromatids separate and are pulled to opposite poles of the cell
Telophase
-nuclear envelope reforms
-spindle apparatus disintegrates
2n=46
46 chromosomes
23 different kinds (22 autosomes + 1 sex chromosome)
