DNA replication is critical to the life of all organisms, insuring that each new cell, as well as each new offspring, gets an accurate copy of the genome.

IPSWICH, Mass., Feb. 14, 2011 /PRNewswire/ -- New England Biolabs has expanded its line of PCR reagents to include OneTaq(TM) and OneTaq Hot Start DNA Polymerases.

UNC scientists who study how cells repair damage from environmental factors like sunlight and cigarette smoke have discovered how a "chaperone" enzyme plays a key role in cells' ability to tolerate the DNA damage that leads to cancer and other diseases.

Suppressing cancer cells' ability to replicate damaged DNA could dramatically enhance the effectiveness of chemotherapy drugs such as cisplatin.

Research could lead to an understanding of how accurate DNA replication occurs to prevent mutations known to result in cancer and genetic diseases DETROIT, Dec.
