DNA replication, the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "semiconservative" in that each strand of the original double-stranded DNA molecule serves as template for the reproduction of the complementary strand. Hence, following DNA replication, two identical DNA molecules have been produced from a single double-stranded DNA molecule. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.

Some combination drug therapies are counter-productive

16. November 2009 04:30
Combination drug therapy has become a staple for treating many infections. For instance, doctors treat extensively drug resistant forms of tuberculosis with one drug that breaks down the pathogen's protective barriers and opens the door for another to deliver the deathblow. [More]

Research reveals that large non-coding RNA in mammals play an important role in telomere maintenance

1. September 2009 04:09
A team of researchers from The Wistar Institute have shown that a large non-coding RNA in mammals and yeast plays a central role in helping maintain telomeres, the tips of chromosomes that contain important genetic information and help regulate cell division. Since this RNA also facilitates the formation of DNA at telomeres-a process that can protect aging cells and destabilize tumor cells-manipulating its expression may be useful in treating cancer and other diseases.
