Furrow formation
The cell cycle begins with interphase when the DNA replicates, the cell grows and prepares to enter mitosis. Mitosis includes four phases, prophase, metaphase, anaphase, and telophase. Prophase is the initial phase when spindle fibers appear that function to move the chromosomes toward opposite poles. This spindle apparatus consists of microtubules, microfilaments and a complex network of various proteins. During metaphase, the chromosomes line up using the spindle apparatus in th… WebStudy with Quizlet and memorize flashcards containing terms like Use the figure to answer the question below.

Furrow formation
Did you know?
A cleavage furrow is an indentation that appears in a cell’s surface when the cell is preparing to divide. It marks the beginning of the cell’s “pinching” its cell membrane and cytoplasm down the middle. Eventually, the cell will pinch itself completely in two, forming two daughter cells. This furrow is created by the same … See more Cells reproduce by splitting in two. After successful cellular reproduction, each half of the parent cell becomes a new, independent cell. … See more 1.
