Gain a clear understanding of spindle fibers: what they are, how they function, why they matter, and their purpose in cell division. Discover the part spindle fibers and cell division play in human growth. Updated: 11/21/2023 Table of Contents What Are Spindle Fibers? Cell Division: How...
Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the...
Any of the tube-shaped structures that help cells maintain their shape and assist in forming the cell spindle during cell division. Microtubules are found in the cytoplasm of the cells of all organisms except bacteria. The American Heritage® Student Science Dictionary, Second Edition. Copyright ...
Supplement Spindle fibers are filaments that form themitotic spindlein cell division, i.e. mitosis and meiosis. They are chiefly involved in moving and segregating thechromosomesduring nuclear division. Spindle fibers are made up of microtubules. Microtubules are polymers of alpha- and beta-tubulindim...
Step-by-Step Solution:1. Understanding the Context: The question asks where chromosomes attach to spindle fibers during cell division. This occurs during a specific phase of the cell cycle.2. Ide
A network of cell fibers that forms in the nucleus during cell division. Duplicate strands of chromosomes attach along the center of the spindle before separating and moving to opposite ends of the cell. See more atmeiosis,mitosis. The American Heritage® Student Science Dictionary, Second Editio...
What is the role of the mitotic spindle? Mitotic spindle formation is a critical event that takes place during prophase. These spindle fibers are necessary to equally divide the chromosomes in the parent cell so that equal, identical copies are found in both daughter cells.What...

Spindle microtubules can be divided into three major classes: kinetochore microtubules, which form k-fibers ending at the kinetochore; interpolar microtubules, which extend from the opposite sides of the spindle and interact in the middle; and astral microtubules, which extend towards the cell cortex...
n. 纺锤,纱锭( spindle的名词复数 );轴; 英英释义 spindle n. (biology) tiny fibers that are seen in cell division; the fibers radiate from two poles and meet at the equator in the middle "chromosomes are distributed by spindles in mitosis and meiosis" ...
