What happens to the thousands of intestinal cells that have tumour-initiating DNA mutations? A study in mouse models shows that most are eliminated by strong negative selection, but those that survive ...

Scientists have revealed parts of the genome that are especially vulnerable to mutations that occur very early on in development. These areas are in the initial portions of genes, where the cell tends ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

A single genetic mutation can lead to completely different diseases, depending on the time and location at which the mutation occurs. This finding emerged from the PhD study conducted by Rocio ...
