As opposed to gene-level mutations, mutations that alter longer stretches of DNA (ranging from multiple genes up to entire chromosomes) are called chromosomal mutations. These mutations often have ...

This means that the damage has multiple chances to generate harmful mutations, which can lead to cancer. While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms ...

The double helix unwinds, and each strand serves as a template for the synthesis of a new ... The genetic code is nearly universal across all living organisms, with only minor variations in some ...

This DNA has suffered a mutation, either through mis-copying (when its parent cell divided), or through the damaging effects of exposure to radiation or a chemical carcinogen.

Researchers uncovered unexpected patterns of mutation inheritance in the trees, revealing that some DNA damage persists unrepaired. In the case of blood stem cells, this can be for two to three years.

Researchers at the Chambers University of Technology have discovered that water is why DNA strands are wrapped around each other and have a helix shape. Understanding how DNA repairs itself could ...
