Question

How prophase I of meiosis differ from prophase in mitosis cell division?

Answer 1

Answer:

Prophase in mitosis-

• prophase is short and is without sub - stages.
• There is no pairing of homologous chromosome (synapsis)using synaptonemal complex and hence, no chance of crossing over and chiasmata formation.
• Prophase chromosomes appear double from the very beginning. KO

Prophase 1 in meiosis:-

• Prophase is prolonged with 5 different sub- stages.
• Homologous chromosome pair using synaptonemal complex during zygotene sub-stage of prophase 1 and often undergo crossing over during pachytene stage hence, forming chiasmata.
• The chromosome appear as single thread initially.
