During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

This forms two replication forks that move along the ... If there were no way to fill this gap, the DNA molecule would get shorter and shorter with every generation. However, the ends of linear ...

Failures in DNA replication can lead to cancer, birth defects or other harm Video shows single pieces of double-helix DNA being copied Single-molecule view gives new insights into this process ...

Now for the first time, scientists have been able to watch the replication of a single DNA molecule, with some surprising findings. For one thing, there's a lot more randomness at work than has ...

as well as cellular processes like DNA replication. The answers to these questions inspire new mathematics and possibly a better understanding of the molecule of life. To understand the ...

When not undergoing replication, DNA molecules float freely ... and every other biomolecule an organism makes. The parts of a DNA molecule that have these instructions are called genes.

Life is thought to have begun when RNA began replicating itself, and researchers have got close to achieving this in the lab ...

They also provide a starting point for design of novel small molecule modulators of polα–primase function that would provide new ways to investigate DNA replication in cells. The Eichman and ...

These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule. During this process, DNA polymerase “reads” the ...

The replication, repair and recombination of the DNA double helix are often considered as separate, isolated processes. But inside the cell, the same DNA molecule is able to undergo any one of ...
