Prophase (from Ancient Greek προ- (pro-) 'before' and φάσις (phásis) 'appearance') is the first stage of cell division in both mitosis and meiosis. Beginning...

replication, meiotic cells enter a prolonged G2-like stage known as meiotic prophase. During this time, homologous chromosomes pair with each other and undergo...

start of the next. These stages are preprophase (specific to plant cells), prophase, prometaphase, metaphase, anaphase, and telophase. During mitosis, the...

selection to act on. In prophase I of meiosis I, each chromosome is aligned with its homologous partner and pairs completely. In prophase I, the DNA has already...

oocytes needed for future ovulations, and these oocytes are arrested at the prophase I stage of meiosis. In humans, as an example, oocytes are formed between...

not pass this checkpoint, it results in the cell exiting the cell cycle. Prophase is the first stage of division. The nuclear envelope begins to be broken...

first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage. In interphase, the cell gets itself ready...

phases of genetic recombination, which occurs in the pachytene stage of prophase I of meiosis during a process called synapsis. Synapsis begins before the...

meiotic crossing over. It then stops in early prophase. Mammalian oocytes are maintained in meiotic prophase arrest for a very long time—months in mice,...
