WebFaulty instructions lead to a protein that does not function normally. Each successive cell division will give rise to daughter cells with even more accumulated damage. Eventually, all checkpoints become non-functional, and rapidly reproducing cells that push out healthy cells, resulting in a tumor or leukemia (blood cancer). Web29 de out. de 2024 · DNA replication errors, especially those occurring at regions that are hard to replicate, called fragile sites, can cause breaks in DNA. This can lead to cancer, primarily by making it more likely that fragments of chromosomes rearrange themselves, activating genes that lead to uncontrollable cell division.
