Select incorrect statements.

1. Diplotene stage is not recognized by the dissolution of the synaptonemal complex.
2. Recombination nodules contain a recombinase enzyme.
3. Interkinesis is generally short-lived.
4. In anaphase II separation of homologous chromosomes (bivalent) separate to opposite poles.

Options:

Answer:
C
Solution:

In the diplotene stage, the synaptonemal complex starts dissolution or disintegrating and the chromosomes start separating after crossing over. Recombination nodules contain a recombinase enzyme which helps in the process of recombination. Separation of homologous chromosomes (bivalent) occurs during anaphase I and this is known as disjunction, it results in a reduction in chromosome number to half. In anaphase II chromatids of a chromosome separate to opposite poles with the splitting the centromere taking place. Interkinesis is the resting stage between two meiotic divisions and generally short-lived.
