DNA Replication
In the S phase of the cell cycle, DNA replication takes place, resulting in the synthesis of identical copies of each chromosome. This is essential for mitosis to occur because each daughter cell needs to receive a complete set of chromosomes. Without the S phase, there would not be enough genetic material to distribute to the daughter cells during mitosis.
Mitosis and cytokinesis occur during the M phase (mitotic phase) of the cell cycle. This phase is characterized by cell division, where the cell replicates its DNA and divides into two daughter cells.
Prophase.
Mitosis occurs during the last phase- Telophase.
It occurs before mitosis, in the S-phase (synthesis) of interphase.
DNA replication occurs during the S phase of the cell cycle, which is before mitosis begins.
Mitosis
Mitosis occurs during the cell cycle in the M phase. This phase follows the G2 phase and is essential for cell division and reproduction. During mitosis, the cell nucleus divides into two identical daughter nuclei.
in what phase of meiosis does synapse occur ?
The first phase in mitosis is prophase, during which the chromosomes condense, the nuclear envelope breaks down, and the mitotic spindle fibers begin to form.
It usually occurs in telophase of mitosis and in the M (mitotic) phase.
The phase that happens only once in meiosis is prophase I, which is characterized by the pairing of homologous chromosomes and the exchange of genetic material through crossing over. This phase is unique to meiosis and does not occur in mitosis.
