DNA is an example of a complex biological polymer called a nuclei acid. Nucleic acids are made up of many smaller sub units called nucleotides. The components of a DNA nucleotide are deoxyribose, phosphate group, nitrogen group. There are four possible bases in a DNA molecules which includes adenine, cytosine, guanine and tymine.
Examining tumor tissue for driver mutations can help plan treatments that stop cancer cells from growing.
tumors was EGFR, followed by TP53 (18%), SETD2 (11%) and SMARCA4 (11%). More than 72% (81/112) of cases have mutations in at least one driver gene.
For example, the TP53 tumor suppressor gene is a driver gene, but it is only functional when both alleles of her TP53 gene are mutated. Furthermore, mutations can act as drivers only at certain stages of cancer.
