Prophase (from

first stage of cell
division in both
mitosis and meiosis. Beginning...

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

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