While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

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 ...

Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body's typically efficient DNA repair machinery and potentially affecting our health ...

Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. UCLA researchers, using an experiment that elucidated the function of tens of thousands of ...

A new long-read sequencing technique has helped researchers investigate how DNA mutations arise in a variety of contexts. A collaboration of researchers led by NYU Langone Health and NYU Grossman ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Lung cancer cases are on the rise in non-smokers around the world, and air pollution could be an insidious, contributing factor. A genome study has now found that outdoor smog and soot are strongly ...

A reanalysis of whole-genome data from 130 children conceived after the Chernobyl disaster has identified a statistically significant increase in a specific type of DNA mutation in the offspring of ...
