Question: What is the role of the spindle fibers during mitosis group of answer choices?

Spindle fibers attach to chromosomes and pull them towards different poles of the cell during the final phases of mitosis. The result is two identical cells with the same chromosomes.

What is the role of the spindle fibers during mitosis quizlet?

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 mitotic spindle.

What happens if spindle fibers don’t form?

For herbicides with this mode of action, the prophase sequence is normal, but without the spindle apparatus, chromosomes are unable to move into the metaphase configuration and daughter chromosomes cannot migrate to their respective poles.

What is the purpose of spindle fibers during cellular division LUOA quizlet?

What is the purpose of spindle fibers during cellular division? Chromosomes are pulled apart and move towards opposite sides of the cell during this phase.

What is a spindle what is its function quizlet?

Spindle. Definition: Fan-like structure made of microtubules that helps separate the chromosomes during mitosis. Cyclin. Definition: One of a family of proteins that regulate the cell cycle in Eukaryotic cells.

Why do spindle fibers shorten?

If this concept is correct, the spindle microtubules attached to the kinetochores of the sister chromatids, shorten by depolymerization (removal) of protein subunits at their polar ends. This would shorten the microtubule and “pull” on it, tugging the chromosome half towards that pole.
