Poor dna repair mechanisms and cancer
WebDNA damage is well recognized as a critical factor in cancer development and progression. DNA lesions create an abnormal nucleotide or nucleotide fragment, causing a break in one or both chains of the DNA strand. When DNA damage occurs, the possibility of generated mutations increases. Genomic instability is one of the most important factors that lead to … WebFirst, I identified the molecular mechanism that governs the DNA binding kinetics for the tumor suppressor p53, the most commonly mutated …
