Malignant cells adopt different pathway for genome duplication
For one of our cells to give birth to two daughter cells, it must first replicate its DNA which consists of around 6.4 billion pairs of nucleotides. The double-stranded DNA opens up like a zipper, producing a ‘replication fork’ upon which a group of enzymes move about. Present in different regions in the DNA, the forks move with the progression of the replication. Cell proliferation is controlled in particular by specific genes known as proto-oncogenes…
