etapas de la mitosis: profase, metafase, anafase y telofase, imagenes y descripcion de cada fase Flashcards
What is the first stage of mitosis?
Prophase
During which phase do chromosomes become visible?
Prophase
True or False: The nuclear envelope breaks down during prophase.
True
What structure forms during prophase that helps separate chromosomes?
The mitotic spindle
What is the second stage of mitosis?
Metaphase
During metaphase, where do the chromosomes align?
The metaphase plate
Fill in the blank: In metaphase, chromosomes are attached to spindle fibers at their _______.
centromeres
What is the third stage of mitosis?
Anaphase
During anaphase, what happens to the sister chromatids?
They are pulled apart to opposite poles of the cell.
True or False: Anaphase ensures that each daughter cell will receive an identical set of chromosomes.
True
What is the final stage of mitosis?
Telophase
During telophase, what happens to the nuclear envelope?
It re-forms around each set of chromosomes.
Fill in the blank: In telophase, the chromosomes begin to _______.
decondense
What is cytokinesis?
The process that divides the cytoplasm of a parental cell into two daughter cells.
True or False: Cytokinesis occurs simultaneously with telophase.
True
Which phase is characterized by the disappearance of the spindle apparatus?
Telophase
What visual characteristic is associated with prophase?
Visible chromosomes and a disintegrating nuclear envelope.
What visual characteristic is associated with metaphase?
Chromosomes lined up at the metaphase plate.
What visual characteristic is associated with anaphase?
Sister chromatids moving toward opposite poles.
What visual characteristic is associated with telophase?
Two distinct nuclei forming in the cell.
What happens to the spindle fibers during telophase?
They disassemble.
What is the role of the mitotic spindle during mitosis?
To separate chromosomes during cell division.
Which phase of mitosis is the shortest?
Anaphase
During which phase are chromatids considered chromosomes?
Anaphase
