Question

Differences between prophase of mitosis and prophage 1 of meiosis

Answer 1

Mitosis prophase

In prophase condensation of basically thin thread like chromosomes starts. due to this, they become short and thick and they start to appear along with their pairs of sister chromatids. Centrioles duplicate and each Centriole moves to opposite poles of the cells . Nuclear membrane and nucleolus start to disappear.

Answer 2

Difference between Prophase of Mitosis and Prophase 1 of Meiosis:

Prophase of Mitosis:

• It appears in somatic cells.
• It is very short phase.
• Formation of chiasma is not seen.
• No crossing over.
• Pairing of homologous chromosome doesn’t take place.

Prophase 1 of Meiosis:

• It occurs in germ cells.

• It is very long phase.

• Formation of chiasma is seen.

• Occurrence of crossing over.

• “Pairing of homologous chromosome occurs”.
