Cell divison

What is mitosis?

Mitosis is the process by which a eukaryotic cell divides its nucleus and contents to produce two identical daughter cells, each with the same number of chromosomes as the original cell.

What is the first phase of mitosis?

prophase

What is the second phase of mitosis

metaphase

What is the third phase of mitosis?

anphase

what is the fourth phase of mitosis?

telophase

What is it called when the cytoplasm seperates into two daughter cells

cytokinesis

what is it called when Chromatin condenses into visible chromosomes (each with 2 sister chromatids)

prophase

what is it called when Chromosomes line up at the metaphase plate (center of the cell)

Spindle fibers attach to centromeres

metaphase

What is it called when Sister chromatids are pulled apart to opposite poles of the cell

Each chromatid is now considered a separate chromosome

anaphase

what is it called when Chromosomes begin to uncoil back into chromatin

Nuclear envelopes reform around the two sets of chromosomes

Spindle fibers break down

telophase

Chromatin

Chromatin - uncoiled DNA in the nucleus

Chromosome

Chromosome - condensed DNA, visible during mitosis

Sister chromatids

Sister chromatids - identical halves of a duplicated chromosome

Sister chromatids

Sister chromatids - identical halves of a duplicated chromosome

Spindle fibers

Spindle fibers - structures that help pull chromatids apart

Centrioles

Centrioles - structures in animal cells that organize spindle fibers
