WebApr 4, 2024 · O 6-methylguanine-DNA methyltransferase (MGMT) is a DNA repair enzyme that maintains the stability of genetic information.MGMT is a strong prognostic biomarker in patients with glioblastoma. However, the effect of its gene hypermethylation and expression on the survival rate of head and neck cancer (HNC) patients is still disputed. WebIn the third step in the process, the DNA polymerase replicates DNA by extension from the 3’ end of the primer, making a new DNA strand. At the end of the first cycle, there are twice as many DNA molecules, just as in cellular replication. But in PCR, steps 1-3 are repeated, usually for between 25 and 30 cycles.
