Cellular organization of genetic materials
Before the cell can divide to form genetically identical daughter cells, all of this DNA must be copied or replicated then the two copies must be separated so that each daughter cell ends up with a _______________
Complete Genome
What does the cell do in preparation for cell division
the chromosomes replicate which allows them to consist of 2 identical sister chromatids that are joined by cohesion
in what phase do the chromosomes appear condensed and the nuclear envelope is not apparent.
Prophase
the cells genetic instructions for a cell
A Genome
The structures that DNA molecules are packaged into to be replicated and distributed.
Chromosomes
What is the division of cytoplasm?
Cytokinesis
In which phase do the spindle fibers pull apart the chromosomes?
Anaphase
A region made up of repetitive sequences in the chromosomal DNA
Centromere
How many chromosomes does each Somatic cell have?
46 (2 sets of 23 from each parent)
After the sister chromatids separate where do they go?
They move into 2 new nuclei one forming at each end.
the longest part of the cell cycle
Interphase
The complex of DNA and proteins that makes up eukaryotic chromosomes
Chromatin
What kind of cell division do eukaryotes have that prokaryotes do not?
Meiosis
What does eukaryotic cell division consist of?
Mitosis and Cytokinesis
The phase in which separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes
Telophase
Any cell in a multicellular organism except a sperm or egg or their precursors
Somatic Cell
how many chromosomes do individual gametes contain?
23
What happens when the cohesion is broken?
Chromatids separate and become the chromosomes of the new daughter cells
What is the order of the phases of Mitosis
interphase Prophase metaphase anaphase and telophase
a variation of cell division that yields daughter cells with only 1 set of chromosomes
Meiosis
