What remains paired during Anaphase I that differs from mitosis?
Understand the Problem
The question is asking about the differences in chromosome behavior between Anaphase I of meiosis and mitosis, specifically which structures remain paired during Anaphase I.
Answer
The sister chromatids remain paired.
The sister chromatids remain paired at the centromere during Anaphase I of meiosis, which differs from mitosis.
Answer for screen readers
The sister chromatids remain paired at the centromere during Anaphase I of meiosis, which differs from mitosis.
More Information
During Anaphase I of meiosis, homologous chromosomes are separated, but the sister chromatids, joined at their centromeres, remain together. In contrast, during mitosis, sister chromatids separate and move toward opposite poles during anaphase.
Tips
A common mistake is to confuse Anaphase I of meiosis with Anaphase II or mitosis, where sister chromatids do indeed separate.
