Multiple Choice
During anaphase I of meiosis, what separates and moves toward opposite poles of the cell?
A
Chromosomes decondense into chromatin fibers
B
Homologous chromosomes (each still consisting of two sister chromatids)
C
The nuclear envelope re-forms around each set of chromosomes
D
Sister chromatids of each chromosome
Verified step by step guidance1
Recall the key events of meiosis I, particularly during anaphase I, which is the stage where homologous chromosomes are separated.
Understand that during anaphase I, the homologous chromosome pairs (each consisting of two sister chromatids) are pulled apart by spindle fibers toward opposite poles of the cell.
Note that sister chromatids remain attached at their centromeres during anaphase I and do not separate until anaphase II.
Recognize that chromosomes do not decondense into chromatin fibers during anaphase I; this typically happens later during telophase.
Conclude that the correct structure moving to opposite poles during anaphase I is the homologous chromosomes, each still made up of two sister chromatids.
