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 ...

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 ...

Circulating tumor DNA (ctDNA), small pieces of DNA released from dying tumor cells into the bloodstream, can be easily and non-invasively identified and examined through a simple blood test. This ...

Researchers are adding new evidence to the emerging concept that 'silent' or synonymous mutations may have crucial consequences. Their study showed how a synonymous mutation in one gene can ...

Bowel cancer cells have the ability to regulate their growth using a genetic on-off switch to maximize their chances of survival, a phenomenon that's been observed for the first time by researchers at ...

New research published in Nature Communications into hidden mutations in mitochondrial DNA has uncovered how high mutational levels coincide with later life and link to aging markers. Mitochondria are ...

There are some genes that can promote cancer; they are sometimes called oncogenes, and in tumor cells, mutations are often found in these genes. When they are functioning normally, oncogenes are often ...

Is Obesity Genetic or Environmental? Get All the Details This article was reviewed by Lynn Marie Morski, MD, JD. Key ...

Mice pups conceived with in vitro fertilization (IVF) in the lab have slightly increased rates of DNA errors, or mutations, compared to pups conceived naturally, a new study on artificial reproductive ...

This module is a replica of a strand of DNA for eye color using light patterns controlled by an Arduino. The four light colors, red, green, blue, and yellow, represent the four nucleotide base pairs, ...
