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

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that ...

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 ...
