DNA Replication is Semiconservative When the replication process is complete, two DNA molecules â identical to each other and identical to the original â have been produced. Each strand of the original molecule has remained intact as it served as the template for the synthesis of a complementary strand.
At first the cells have the same number of chromosomes as mitosis. DNA replication occurs, giving a total of 46 chromosomes (or 23 chromosome pairs) and 92 chromatids (or 46 chromatid pairs). Meiosis I: In meiosis I, the homologous chromosomes separate. In this case, the pairs of sister chromatids are still attached to each other.
