Carcinogens cause mutations by damaging the way the cell repairs DNA or makes proteins. If the cancer cell is not able to repair this DNA damage, then it will keep dividing to make new cells and will pass the mutation on to all the new cells that are made.

WebDNA damage through exogenous and endogenous stressors is common in normal cells. DNA damage repair (DDR) occurs via four major pathways; nucleotide excision repair (NER), base-excision repair (BER), MMR, HR, and non-homologous end joining (NHEJ) [].SSBs are repaired using the complimentary healthy strand mainly by BER, whereas DSBs repair …

WebSection Summary. DNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After replication, each DNA has one parental or “old” strand, and one daughter or “new” strand. Errors made during replication are typically repaired. WebNormal cells can repair themselves if their genes become damaged. This is known as DNA repair. Cells self destruct if the damage is too bad. Scientists call this process apoptosis. In cancer cells, the molecules that decide whether a cell should repair itself are faulty. For example, a protein called p53 usually checks if the cell can repair ...

WebCancer cells can divide many more times than this, largely because they express an enzyme called telomerase, which reverses the wearing down of chromosome ends that normally happens during each cell division ^4 4. Cancer cells are also different from normal cells in other ways that aren’t directly cell cycle-related.
