Read the following cellular events: I. Formation of synaptonemal complex II. Splitting of centromere III. Formation of recombination nodules IV. Alignment of bivalents on the equatorial plate V. Attachment of spindle fibres to kinetochores How many of the above events occur exclusively during meiosis and are never observed in mitosis?

Step-by-step solution

Let us evaluate each event: I. Formation of synaptonemal complex occurs during zygotene of Prophase I in meiosis. It is absent in mitosis. II. Splitting of centromere occurs during anaphase of mitosis and anaphase II of meiosis. It is not exclusive to meiosis. III. Formation of recombination nodules occurs during pachytene of Prophase I in meiosis. It is absent in mitosis. IV. Alignment of bivalents on the equatorial plate occurs during metaphase I of meiosis. In mitosis, individual chromosomes align at the metapha
