Which one of the following statements about mitosis is correct?(a) One

1.	Which one of the following statements about mitosis is correct?(a) One nucleus gives rise to 4 nuclei(b) Homologous chromosomes synapse during anaphase(c) The centromeres separate at the onset of anaphase(d) Non-sister chromatids recombine
Answer» Answer is : (c) The centromeres separate at the onset of anaphase In anaphase, sister chromatids separate from centromeres so, number of chromosome becomes double. Other statements about mitosis can be corrected as Mitosis is a single nuclear division that results in two nuclei. Synapsis takes place during prophase-I of meiosis not during mitosis. Non-sister chromatids recombine during prophase-I of meiosis. During mitosis, each sister chromatid separates and moves to opposite pole of the cell at anaphase.

Answer»

Answer is : (c) The centromeres separate at the onset of anaphase

In anaphase, sister chromatids separate from centromeres so, number of chromosome becomes double. Other statements about mitosis can be corrected as Mitosis is a single nuclear division that results in two nuclei.

Synapsis takes place during prophase-I of meiosis not during mitosis. Non-sister chromatids recombine during prophase-I of meiosis. During mitosis, each sister chromatid separates and moves to opposite pole of the cell at anaphase.
