Virginia Tech researchers used novel methodology and the university's System X supercomputer to carry out what is probably the first simulation that explores full range of motions of a DNA strand ...

First realistic simulation of DNA unfolding Date: May 25, 2010 Source: Institute for Research in Biomedicine-IRB Summary: The separation of the two DNA strands occurs in millionths of a second.

In addition to the sequence of the base pairs, the instructions are in the packaging--how DNA is folded within a cell. ... Researchers conduct first molecular simulation of a long DNA strand.

Telomeres, which consist of single-, double- and four-stranded DNA, shorten after each round of cell division. The repeated telomeric DNA sequence 5′-TTAGGG-3′ does not encode genetic ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this ...

DNA replication is a fundamental process for a cell to ensure that an accurate copy of its genetic material is transmitted to daughter cells at each cell division. Challenges to DNA replication ...

DNA replication and repair are critical processes that ensure the correct genetic material of a biological system is carried on. DNA continually undergoes a process of replication and division and ...

Problems during DNA replication can cause the genome to become disorganized, which is often a key step on the route to cancer. Some genetic diseases, too, result from problems with DNA replication.

Their findings, which were published March 7 in Science, one of world’s leading scientific journals, not only reveal new details about how secondary DNA structures like G4s can impede DNA replication, ...

DNA replication occurs in the S phase of the cell cycle. DNA replication is the process where DNA copies itself. This happens so that old cells can make new cells.
