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 ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues ...

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 ...

Successful DNA replication in cyanobacteria depends on the circadian clock Date: May 18, 2021 Source: University of Chicago Medical Center Summary: A new study has found that the photosynthetic ...

The first step in DNA replication requires the assembly of a group of proteins called the Origin Recognition Complex (ORC). Researchers have determined how the ORC assembles during the cell ...

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 ...
