Thymine suffers more UV damage than uracil in lab tests, but its damage pathways could help explain its place in DNA.

A study at Texas A&M University suggests that thymine may have helped early genetic molecules survive by directing that damage into a form that was easier to reverse. The findings, published in ...

Scientists have long sought to understand the complex origins of intelligent life. It remains unclear how biological systems ...

During the process of transcription, DNA is converted to RNA, a complex molecule that is able to carry genetic information outside of the cell's nucleus. This page guides you through the biochemical ...

Origins of life and molecular evolution research using biophotonics to study DNA bases under ultraviolet radiation.

Scientists unlock a groundbreaking discovery about the origins of life with absorption, fluorescence and Raman spectroscopy.

NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory. They discovered that an ice sample ...

The decoding of information in a cell's DNA into proteins begins with a complex interaction of nucleic acids. Learn how this step inside the nucleus leads to protein synthesis in the cytoplasm.
