Duplicated chromosomes appear as sister chromatids
Prophase
chromosomes line up at metaphase plate
what is metaphase?
DNA replication and chromosome duplication occurs
Synthesis Phase (S Phase)
Cells are usually in the M phase
False
Identical copies formed by the DNA replication of a chromosome.
What are sister chromatids?
First phase of mitosis
Prophase
Final growth and preparation for mitosis
What is G2 phase?
Largest portion of Cell Cycle (90%)
What is interphase?
Vesicles produced by the Golgi apparatus travel to the middle of the cell and form a cell plate
True
Region on each sister chromatid where they are most closely attached.
What are centromeres?
two daughter nuclei form
What is anaphase/cytokinesis?
In between prophase and metaphase
what is prometaphase?
Formed by vesicles from the golgi in the middle of a plant cell to divide it
what is a cell plate?
Strings of nucleosomes form histones
False
Proteins attached to the centromere that link each sister chromatid to the mitotic spindle.
What are kinetochores?
Nucleoli disappear, mitotic spindle begins to form
What is Prophase?
centrosomes are at opposite poles
Metaphase
stage of mitosis that occurs through cytokinesis
what is anaphase?
Copies join together to form brother chromatids
False
Proteins are responsible for holding the sister chromatids together?
What is cohesin?
Nuclear envelope fragments, microtubules enter nuclear area
Prometaphase
Microtubules shorten, sister chromatids separate and move to opposite ends of the cell
What is anaphase?
Appears due to a contractile ring of actin filaments
What is a cleavage furrow?
Prokaryotes have singular circular DNA
True
Responsible for hydrolyzing cohesin, triggering anaphase.
What is seperase?
