longer.<\/p>\n\n\n\n<p>But it\u2019s actually shorter.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 2: Forgetting Interphase<\/h3>\n\n\n\n<p>Interphase occurs before mitosis and lasts longer than all mitotic stages combined.<\/p>\n\n\n\n<p>However, <strong>interphase is not part of mitosis<\/strong>, so it\u2019s not the correct answer.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Mistake 3: Confusing Anaphase<\/h3>\n\n\n\n<p>Anaphase looks important, but it\u2019s one of the <strong>shortest phases<\/strong>.<\/p>\n\n\n\n<p>Chromosome separation happens quickly.<\/p>\n\n\n\n<hr class=\"wp-block-separator
