Dna is replicated before
WebSep 27, 2024 · DNA replication is the process by which cells make a copy of their DNA before cell division. DNA replication is a semi-conservative process, meaning that one strand of the original DNA molecule serves as a template for the synthesis of a new complementary strand. DNA replication is initiated at specific sites called origin of … WebDNA replication is a crucial process; therefore, to ensure that mistakes, or mutations, are not introduced, the cell proofreads the newly synthesized DNA. Once the DNA in a cell is replicated, the ...

WebIf DNA replication occurred again before meiosis II, the sister chromatids would be replicated and the cells would have four copies of 23 individual chromosomes. At the end of meiosis II, the resulting haploid cell would have two copies of 23 individual chromosomes, a condition that is incompatible with life. WebStage two.
