1) In the prophase of mitosis,

1. homologous chromosomes become paired.
2. the centriole reappears.
3. tetrads of chromatids appear.
4. synapsis takes place.
5. chromosomes are doubled and the duplicate chromotids may be observed.

The prophase is recognized as the phase of mitosis in which the chromatids may be observed in the doubled chromosomes.
