Exposure to mutagens, or mutation-causing agents, can not only bring about changes in DNA but also appear to induce errors when genes are transcribed to make proteins, which may be an important factor in age-related diseases.

Skin is the body's armor, protecting us from disease agents, injury, excessive water loss, and cold and heat. Yet mutations in a single gene, the gene for the protein p63, cause numerous diseases and malformations of the ...

(Phys.org)—Researchers studying Drosophila pachea, a species of fruit fly that lives only in the Sonoran desert, have discovered why it is that the fly is wholly dependent on a single cactus species. It's due, they write ...
RNA editing gives organisms a way to adapt the instructions that their DNA provides for making proteins. Few people would have described RNA editing as a simple process, but a new paper in Nature Communications demonstrates ...

You can think of DNA as a string of letters—As, Cs, Ts, and Gs—that together spell out the information needed for the construction and function of cells. Each cell in your body shares the same DNA. So, for cells to take ...

Proteins, the workhorse of the human cell, help digest our food, carry oxygen through the body, fight off invading microbes, and so much more—but they only function when folded properly into specific, three dimensional ...
