For the stages of the cell cycle, select the correct option.
A. A chromosome is arranged at the equator - Metaphase.
B. Centromere splits and chromatids are separated - Anaphase I.
C. The pairing between homologous chromosomes takes place - Zygotene.
Options:
Answer:
B
Solution:
During metaphase chromosome are arranged at equator to form metaphasic plate and spindle fibre attaches to kinetochore of centromere. Splitting of centromere and separation of chromatids occurs during anaphase of mitosis and Anaphase II of meiosis. In Anaphase I chromosomal pairs separates and this is known as disjunction. Pairing of homologous chromosome occurs during zygotene and is known as synapsis.
