Scientists from the Medical Research Council (MRC) Institute of Genetics and Molecular Medicine (IGMM) at the University of Edinburgh have discovered an enzyme that corrects the most common mistake in mammalian DNA.
A new study led by scientists at The Scripps Research Institute suggests that the replication process for DNAthe genetic instructions for living organisms that is composed of four bases (C, G, A and T)is more ...
The molecular machines that copy DNA in a living cell are amazingly fast and accurate at pairing up the correct bases—G with C and A with T—into each new double helix.
Basic biology textbooks may need a bit of revising now that biologists at UC San Diego have discovered a never-before-noticed component of our basic genetic material.
Why cancer drugs lose their power: Platinum-based cancer drugs destroy tumor cells by binding to DNA strands
(PhysOrg.com) -- For 30 years, the chemotherapy drug cisplatin has been one of doctors' first lines of defense against tumors, especially those of the lung, ovary and testes. While cisplatin is often effective when first ...
A rudimentary form of life that is found in some of the harshest environments on earth is able to sidestep normal replication processes and reproduce by the back door, researchers at The University of Nottingham have found.
Mutant cells that can't copy DNA somehow keep dividing when they shouldn't—with disastrous consequences
Researchers at USC have developed a yeast model to study a gene mutation that disrupts the duplication of DNA, causing massive damage to a cell's chromosomes, while somehow allowing the cell to continue dividing.
