Vedclass · Answer

(A) During cell division,specifically in metaphase,spindle fibers are categorized based on their attachment.$1$. Chromosomal fibers (also called kinetochore fibers or tractile fibers) extend from the spindle poles and attach directly to the kinetochores of the chromosomes.$2$. Continuous fibers (or non-kinetochore fibers) extend from pole to pole without attaching to chromosomes.$3$. Interzonal fibers are found between the separating chromosomes during anaphase.Therefore,the fibers extending from the pole to the kinetochore are called chromosomal or tractile fibers.

The spindle fibers that extend from the pole to the kinetochore are known as:
