What lines up at the metaphase plate during metaphase I of meiosis? What lines up at the metaphase plate during metaphase of mitosis?

A. each chromosome composed of two sister chromatids for meiosis, homologous chromosomes for mitosis

B. homologous chromosomes for meiosis, each chromosome composed of two sister chromatids for mitosis

C. each chromosome composed of two sister chromatids at both

D. each chromosome composed of two sister chromatids for meiosis, each chromosome composed of one sister chromatid for mitosis

E. homologous chromosomes at both 






Answer (B.).,homologous chromosomes for meiosis, each chromosome composed of two sister chromatids for mitosis.

Answer 2

The chromosomes line up along the metaphase plate during the metaphase of mitosis and metaphase II of meiosis.

• In the metaphase of mitosis and metaphase II of meiosis, the lining of chromosomes takes place along the metaphase plate because of the activity of the microtubule spindle fibers originating from the centrosomes situated at the opposite poles of the cell.  

• The attachment of these fibers with the chromosomes takes place with the help of kinetochores at the centromeres of the chromosomes.  

• The region or plane, which is almost equidistant from the two poles of a dividing cell is known as the metaphase plate.
