Select the CORRECT statement from the following.
Options
- ADuring mitosis, endoplasmic reticulum and nucleolus disappear completely at early prophase
- BChromosomes are arranged along the equator during prophase
- CChromosome is made up of two sister chromatids at anaphase of mitosis.
- DA cell plate is laid down during interphase
Correct answer
C. Chromosome is made up of two sister chromatids at anaphase of mitosis.
Step-by-step solution
Mitosis consists of karyokinesis followed by cytokinesis. Karyokinesis includes prophase, metaphase, anaphase and telophase. In prophase, the condensation of chromatin takes place. In metaphase nuclear envelope disintegrates and chromosome condensation completes and chromosomes align at the equator. In anaphase, the chromosomes split and two chromatids separate and thus they start migrating towards the poles. At telophase the chromatids reach the end.
