Which stage of mitosis is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids?
Answer: Anaphase.
Explanation:
The stage of mitosis that is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids is ANAPHASE.
Mitosis is a type of cell division by which a parental cell divides in order to produce two genetically identical daughter cells.Mitosis has four phases prophase, metaphase, anaphase, and telophase.During prophase, chromatin condenses into chromosomes, the nuclear envelope disintegrates and spindle microtubules grow and extend from each pole of the cell.During metaphase, homologous chromosomes line up at the equator plate of the cell, the mitotic spindle is fully developed and it attaches to the kinetochores that appear at the centromeres.During anaphase, chromosomes are separated by the elongation of the mitotic spindle and pulled to opposite poles of the cell.In conclusion, the stage of mitosis that is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids is ANAPHASE.

What is adhesion?The Adhesion happens between two dissimilar molecules or substance. The force of attraction present between the water molecules and the walls of xylem vessels is defined as adhesion.
The capillary action and meniscus ( the curved surface which is formed by any liquid in a cylinder) are the effects of adhesion. The adhesion of water can be easily observed in every day life.
Some examples of adhesion of water are raindrops sticking to the windows, dew drops hanging from the leaves, etc.
