The team’s research, published this week in the Proceedings of the National Academy of Sciences, describes a ribozyme that could create an environment…

Scientists Added Two New Letters To DNA’s Code
If you’ve taken a science class, you’re likely aware that DNA is the body’s instruction manual. But its language is only written in four letters: A, T, C and G. Those who paid extra close attention will remember that RNA, the photocopy of the instructions that the cell actually uses, replaces the Ts with the…
