DNA polymerases are the “Xerox machines” that replicate our DNA. They must work with great precision to keep errors from creeping into our genes. In spite of this precision, they still accept building ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

A research team has discovered that accumulated DNA damage in the retina is a key contributor to age-related macular degeneration and that targeting specific retinal cell types may lead to treatments ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...
