Questions and Answers

What is the primary characteristic of chromosomes during metaphase?

  • They are located at the poles of the cell.
  • They are scattered randomly throughout the cell.
  • They line up across the center of the cell. (correct)
  • They have already divided into individual chromatids.

    • What role do spindle fibers play during metaphase?

  • They separate the chromatid pairs.
  • They ensure the replication of DNA.
  • They connect chromosomes to the centromere. (correct)
  • They help in the formation of new organelles.

    • Which structure joins the sister chromatids during metaphase?

  • Chromatin
  • Centrosome
  • Telomere
  • Centromere (correct)
