As previously mentioned, the location at which a DNA strand begins to unwind into two separate single strands is known as the origin of replication. As shown in Figure 1, when the double helix ...

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 ...

When a cell divides, it makes a copy of its DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds and the strands separate. The nucleotides (A ...

Biological systems are complicated. Though DNA may carry a simple sequence of base pairs, once this information is transcribed into RNA and translated into proteins, this simple sequence can give rise ...

The replication fork is more than just a means for DNA duplication. It is connected to a checkpoint system that keeps the genome intact and prevents cancer. Aa Aa Aa Eukaryotic genomes are ...

Impressively, deleting one copy of Msh3, the CAG expansion rate in MSNs reduced to ... The study provides important therapeutic implications. First, the study tested 6 DNA mismatch repair genes and ...

A study links the loss of DNA methylation across the genome—as is common in cancer—to the disruption of the 3-D compartments that organize the genome and to the timing of DNA replication. Cell lines ...
