Stages of Cell Cycle
The longest phase of the cell cycle.
What is Interphase?
These form the mitotic spindle.
What are microtubules?
Chromosomes before mitosis = 46. Chromosomes at end of mitosis in each cell =
What is 46?
During this phase the centromeres break apart as the separated sister chromatids begin to move to opposite poles
What is Anaphase?
Chromosomes before meiosis = 46. Chromosomes at end of meiosis in each cell =
23
Phase crossing-over occurs
What is Prophase I?
Half of a chromosome in prophase
What is a sister chromatid?
The end result of Mitosis.
What is 2 identical daughter cells?
New daughter nuclear membranes form during this phase.
What is Telophase?
Daughter cells produced
What is 4?
Meiosis division that inculdes homologous pairs.
Meiosis I
Period when interphase begins in a daughter cell
What is the G1 phase?
Cells made by Mitosis.
What are somatic cells?
Spindle fibers first appear during this stage.
What is Prophase?
The end result of Meiosis.
What are 4 genetically different daughter cells?
Four sister chromatids together make up this.
What is a tetrad?
Period of nuclear division
What is Mitosis?
In pairs in some eukaryotic cells
What is a centrioles?
Growth, repair, development
What is reason for Mitosis?
Chromosomes are lined up on the equatorial plate.
What is Metaphase?
Exchanging of corresponding segments of DNA
What is crossing-over?
Phase of Meiosis when sister chromatids separate and move towards the poles.
What is Anaphase II?
Period after DNA is duplicated.
What is the G2 phase?
Cytoplasm apportioned between the 2 daughter cells
What is cytokinesis?
2 sets of chromosomes
What is diploid?
Genes replicate during this phase
What is Interphase?
Number of divisions in Meiosis
What is 2?
The pairing of homologous chromosome sis called
What is Synapsis?
