Here are clear definitions and corrected/paired statements for each term and mitotic stage you listed.
Definitions
- Mitosis: division of a cell’s nucleus into two genetically identical nuclei; includes the stages prophase, prometaphase, metaphase, anaphase and telophase.
- Prophase: chromatin condenses into visible chromosomes; the mitotic spindle begins to form and centrosomes (centrioles in animal cells) start moving toward opposite poles.
- Prometaphase: the nuclear envelope breaks down and spindle microtubules attach to chromosomes at their kinetochores.
- Metaphase: chromosomes line up along the cell’s equatorial plane (the metaphase plate).
- Anaphase: sister chromatids are separated at the centromere and pulled toward opposite poles.
- Telophase: chromosomes reach the poles, begin to decondense (unwrap), and a new nuclear envelope re-forms around each set.
- Cytokinesis: the cytoplasm divides; in animal cells a cleavage furrow forms and pinches the cell into two daughter cells.
- Centriole: a cylindrical organelle in the centrosome of animal cells that helps organize the mitotic spindle.
- Chromosome: an organized structure of DNA and proteins (histones) found in cells; after DNA replication each chromosome consists of two sister chromatids joined at the centromere.
- Sister chromatids: the two identical copies of a replicated chromosome, joined at the centromere, that separate during anaphase.
Corrected sentences matched to stages
- “Chromosomes get pulled at the centromere; the two identical copies (sister chromatids) get pulled apart.” → Anaphase.
- “Chromosomes reach the poles. The nuclear membrane begins to form. Chromosomes begin to unwrap (decondense).” → Telophase.
- “Cleavage furrow forms, pinching the cell to form two daughter cells.” → Cytokinesis.
(Note: “ADN” is the Spanish abbreviation for DNA; in English use “DNA”.)
