Question

Distinguish b/t prophase of mitosis and prophase of meiosis

Answer 1

Dear student,

Mitotic prophase is a comparatively short phase.
The main events include:
Presence of two identical copies or sister chromatids which are attached at the centromere.
Condensation of chromosomes.
The movement of centrosomes mitotic spindle formation
Nuclei begin to break down.
Absence of crossing over, synopsis, chiasma, and recombination

Prophase 1 of meiosis is a long phase.
During prophase 1 following events occurs
Condensation of chromosomes
Occurrence of sister chromatids
Pairing of homologous chromosomes
Formation of synaptonemal complex or tetrad
Genetic exchange between non-sister chromatids or crossing over occurs
Formation of chiasmata
Beginning of spindle apparatus formation

Prophase 2 is almost similar to mitotic prophase. But in prophase 2, haploid number of chromosomes are involved.
