One potential reason for their fluctuating speed, Prof. Pigolotti speculates, is that there may be limits on resources needed for replication, such as nucleotides – the building blocks of DNA.

Scientists say their work on a critical step in DNA replication will provide new insights into a fundamental process of life and driver of many different diseases, including cancer. They report ...

The fact that TAg was expressed after DNA replication suggested it was expressed too late to be responsible for driving cells into replicating their DNA. Sunnie Thompson, Ph.D. TAg expression and ...

Scientists have created an unprecedented 3-dimensional structural model of a key molecular "machine" known as the BAF complex, which modifies DNA architecture and is frequently mutated in cancer ...

Self-replication is a complicated process -- DNA, the basis for life on earth today, requires a coordinated cohort of enzymes and other molecules in order to duplicate itself.
