Cells primarily repair double-strand breaks by either rejoining the broken DNA ends or by using another DNA molecule as a template for repair. However, my team and I discovered that RNA, a type of ...

Scientists have created an artificial RNA system that can copy itself using simple building blocks and temperature changes.

While great strides have been made in exploring the world of RNA, mysteries remain—and one approach to solving them is to look at what exactly a strand of RNA is doing in a cell in real time. At ...

In Biology 101, we learn that RNA is a single, ribbon-like strand of base pairs that is copied from our DNA and then read like a recipe to build a protein. But there's more to the story. Some RNA ...

Within a few hundred milliseconds, the DNA double helix unwinds to form a node known as the transcription bubble, so that one exposed DNA strand can be copied into a complementary RNA strand.
