Question

Which of the following occurs in meiosis but not in mitosis?

• A. Attachment of spindle fibres to the kinetochores
• B. Pairing of homologous chromosomes at the metaphase plate
• C. Replication of DNA prior to the start of cell division
• D. Separation of sister chromatids at anaphase

Answer 1

The correct option is B

Pairing of homologous chromosomes at the metaphase plate

The pairing of homologous chromosomes, called synapsis, does not occur in mitosis. Synapsis only occurs in meiosis.

The attachment of spindle fibres to the kinetochores of chromosomes, replication of DNA prior to the start of cell division and the separation of sister chromatids, all occur in both mitosis as well as meiosis.
