Mitosis Flashcards
what are centromeres?
where the sister chromatids are attached.
what are chromosomes?
structures that contain genetic materials passed down from generations.
what are sister chromatids?
two structures that have identical DNA.
what are the four phases of mitosis?
Prophase
Metaphase
Anaphase
Telophase
what is a chromatin?
the relaxed form of DNA in the cell’s nucleus.
what is a spindle apparatus?
a structure that helps move and organizes chromosomes before cell division.
made of spindle, centrioles, and aster fibers
what is anaphase?
the third phase of mitosis.
the sister chromatids are pulled apart and to opposite ends of the cell.
what is cylins?
proteins that bind to enzymes.
what is cytokinesis?
the third stage of the cell cycle
where the cytoplasm divides and creates a new cell.
what is interphase?
the first stage of the cell cycle where the cell grows and replicates DNA.
what is metaphase?
the second stage of mitosis.
where the sister chromatids are pulled by motor proteins along the spindle apparatus.
what is metaphase?
the second stage of the cell cycle.
DNA is divided into two sister chromatids.
what is prophase?
the first stage of mitosis.
the chromatin condenses into chromosomes and the nucleus disappears.
what is telophase?
the last phase of mitosis.
the chromatids arrive at the cell’s poles and began to decondense.
what is the cell cycle?
a cycle of cells reproducing and dividing.
