Definition

1. Noun:
   • A stage of cell division: "anaphase" is the stage in mitosis or meiosis when the paired chromosomes separate and move toward opposite poles of the dividing cell.

Usage

• "Anaphase" is a specific biological term used to describe a precise moment in the process of cell division. It is used in scientific, academic, and educational contexts.

Examples

• Noun:
  • During anaphase, the sister chromatids are pulled apart by the spindle fibers.
  • Errors in chromosome segregation during anaphase can lead to genetic disorders.

Advanced Usage

• "Anaphase onset": the beginning of the anaphase stage.
  • The cell cycle checkpoint ensures proper chromosome attachment before anaphase onset.
• "Anaphase lag": a delay in the movement of a chromosome during anaphase.
  • Anaphase lag can result in one daughter cell missing a chromosome.

Variants and Related Words

• Anaphasic (adj): relating to or characteristic of anaphase.
  • The researcher studied the anaphasic movements in detail.

Synonyms

• Separation phase: a descriptive synonym emphasizing the key event of this stage.
• Chromosome migration stage: a descriptive term highlighting the movement of chromosomes.

Related Terms (Contextual)

• Mitosis: the process of cell division that includes prophase, metaphase, anaphase, and telophase.
• Meiosis: the process of cell division that reduces chromosome number, also including anaphase I and anaphase II.
• Spindle apparatus: the structure that pulls chromosomes apart during anaphase.

Noun

1. the stage of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle
