39.A characteristic feature of meiosis is: A. Two DNA replication and one division of cytoplasm B. A single DNA replication and one division of cytoplasm C. Two DNA replication cycle and two division of cytoplasm D. A single DNA replication and two division of cytoplasm
Option D Meiosis, as we know, is called as Reductional division where the number of chromosomes is reduced to half from parent to daughter cell. It involves two cycles - Meiosis I and Meiosis II where nuclear and cell division takes place but DNA replication takes place once only. While meiosis I take place after the cell has completed the replication of DNA of parent material and thus identical sister chromatids is formed. While since it is a reductional division so we know four daughter cells are formed having half the number of chromosomes as of parent cell. Moreover, Meiosis never involves the pairing of non-homologous chromosomes and no recombination occurs between them. So, the Incorrect statement with respect to meiosis is 'Meiosis involves the pairing of non-homologous chromosomes and recombination between them.'.
