Mitosis + Miosis Flashcards
What is Mitosis?
Mitosis is a process of cell division that results in two daughter cells and is essential for replenishing tissue.
What exactly are the stages of mitosis?
Prophase, metaphase, anaphase, telophase, and cytokenesis.
What is the Prophase stage?
The chromatin condenses into visible chromosomes then the Nuclear membrane disintegrates
What is the metaphase?
The chromosomes line up in the center and spindle fibers attach to the centromeres
What is the Anaphase
The chromosomes are pulled apart by the spindle fibers and they move to opposite parts of the cell.
What is the Telophase?
After the CHROMATIDS are in opposite parts of the cell, the nuclear membrane reforms and the chromosomes decondense into chromatin.
What is cytokinesis
Final step, the cytoplasm divides and forms two daughter cells.
How does the step cytokinesis differ between plant and animal cells?
In an animal cell the cleavage furrow forms to split the cells
Plant cells- the cell plate forms to split the cells
What is an allele?
Many versions of a specific gene
What be a centriole?
It be an organelle in animal cells and pwoduces spindle fibers
What’s a centromere?
It is a region of DNA that binds chromosomes together
What’s a chromatid
1/2 of a chromosome which is produced when DNA wraps around a protein.
What is a chromatin?
It is a material that makes up chromosomes
What’s a diploid?
It is a set of chromosomes in a cell.
What’s a haploid?
1/2 of homogenous chromosomes in a cell.
