Multiple Choice
During telophase I of meiosis, which event typically occurs in most organisms?
A
DNA replication occurs to duplicate each chromosome before the next division
B
Sister chromatids separate at the centromeres and move to opposite poles
C
Homologous chromosomes have reached opposite poles, and nuclear envelopes may begin to reform around each haploid set
D
Crossing over between homologous chromosomes occurs as the synaptonemal complex forms
Verified step by step guidance1
Recall the stages of meiosis and the key events that characterize each phase, focusing on meiosis I and meiosis II.
Understand that DNA replication occurs only once before meiosis begins, specifically during the S phase of interphase, and does not happen again during meiosis.
Recognize that during anaphase I, homologous chromosomes (not sister chromatids) separate and move to opposite poles, while sister chromatids remain together until meiosis II.
Identify that telophase I is the stage where homologous chromosomes have reached opposite poles, and nuclear envelopes may start to reform around each haploid set of chromosomes.
Note that crossing over occurs earlier during prophase I when the synaptonemal complex forms, not during telophase I.
