Definitions:

Anaphase

A stage during cell division where replicated chromosomes are split and the newly-copied chromosomes are moved to opposite poles of the cell, leading to cell division.

Prophase

The first stage of cell division in both mitosis and meiosis where chromosomes become visible and the nuclear envelope dissolves.

Motor Proteins

Proteins that convert chemical energy into mechanical work, facilitating movement within cells, such as the transportation of cellular cargoes.

Actin

A protein that forms filaments and is involved in various types of cell motility and structure.
