The spindle fibres are composed of  which of the following?

 

Solution: Spindle strands shape a protein structure that partitions a cell's hereditary fabric or chromosomes amid cell division. ∙ Amid both sorts of atomic division (mitosis and meiosis) the spindle is required to equitably separate the chromosomes in a parental cell into two daughter cells. ∙ Arrangement of axle strands happen in prophase of the cell cycle from centrioles show at inverse closes of partitioning cell.

The spindle fibers are also called the mitotic spindle. It refers to the cytoskeletal structure of eukaryotic cells that forms using division to separate sister chromatids between daughter cells. They are composed of proteins called microtubules.

Hence, the correct answer is option 1.
