A new study from King Abdullah University of Science and Technology (KAUST), published in Nature, captures the moment DNA ...

Using cutting-edge cryo-electron microscopy, the team of scientists were able to visualize a helicase enzyme (nature’s DNA unzipping machine) in the process of unwinding DNA. DNA helicases are ...

Most cells in the human body each contain about six feet of DNA. Yet the nucleus, where DNA is coiled, is no larger than a ...

Deoxyribonucleic acid (DNA) replication is fundamental to life, yet the precise mechanics of how helicases unwind the genome for replication remain unclear. A recent study published in Nature used ...

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 ...

The RF is a multiprotein complex with helicase and DNA synthesis activities. It is called a fork because the structure resembles a two-pronged fork. The helicase activities unwind DNA in front of ...
