Here's what happens: 1  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). 2  Meiosis I: In meiosis I, the homologous chromosomes separate.
DNA Replication. DNA replication is the process of copying the DNA in a cell so that there are two copies. This is done in preparation for cell division, or mitosis. Before a cell divides, the DNA must be copied so that there is a copy for each of the resulting daughter cells.imilarities. Both DNA replication and transcription involve binding complementary nucleic acids to DNA, yielding a new strand of either DNA or RNA. Both processes can lead to errors if an incorrect nucleotide is incorporated.
