Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study uncovers how amino acids could have linked with RNA under early Earth conditions, shedding light on the origin of life ...

Ask a friend what DNA is and, chances are, they have a general idea. Seventy years after scientists discovered the two-stranded helix, DNA (deoxyribonucleic acid) is widely understood as the keeper of ...

RNA is one of the bodies most vital molecules, and it comes in a few forms. For example, messenger RNA fills an essential role in gene expression by copying the sequences of active genes, which are ...
