In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in ...

DNA replication is a fundamental biological process that enables the accurate duplication of an organism’s genetic material. This intricate mechanism ensures that each new cell receives a ...

Experiments in flies and other model systems reveal that retrotransposons ‘hijack’ a DNA-repair pathway in host cells to produce circular DNA, enabling their replication and subsequent ...

The cell controls the start of DNA replication in a two-step process. The whole goal of the process is to control the actions of a crucial enzyme—called a helicase—that unwinds the DNA double ...

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

The whole process of DNA replication, in human cells, takes about eight hours. There is still plenty to be worked out. For one thing, the DNA that’s being copied is not a naked double helix.

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study.

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified.

The radiation in space is not great for biological health. Space radiation is known to damage DNA. Many types of human cells have to frequently divide to replace cells that are worn out, old, or ...

Northwestern Medicine scientists have discovered how a common virus linked to birth defects and chronic illness manipulates ...
