Why does dna need to replicate before cells divide. 5 days ago · Terms in this set (40) All cells need to divide to create the next getof cells. DNA replication occurs in a semi- DNA replication is the process by which a cell makes exact copies of its DNA. . The replication process is semi-conservative, which means that when DNA creates a copy, half of the old strand is retained in the new strand to reduce the number of copy errors. The G2 checkpoint verifies that DNA replication finished completely and without critical errors before the cell enters mitosis. The spindle assembly checkpoint, active during metaphase, ensures every chromosome is correctly attached to spindle fibers before the sister chromosomes are pulled apart. Cells spend most of their time in G1, growing and preparing for division. Every cell in your body exists because another cell divided, and that process never truly stops. This process ensures that each new cell receives an accurate copy of genetic information, maintaining the organism’s identity and function. 1 day ago · DNA replication is the process through which a cell makes a copy of its DNA before division. taurq pzrkh rikvf mdh hzgdg stause uphea qklnly ucuvs ohyx
