The Tactile DNA puzzle is a tool to teach visually impaired students the chemistry and structure of DNA. ... Each nucleotide consists of 3 components. A phosphate group, deoxyribose sugar, and a ...

What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this mystery. Their experiments show that ribose binds more readily and ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these ...

Abasic sites in DNA are generated by hydrolysis of the N-glycosidic bond that connects the base to the deoxyribose sugar. This occurs either spontaneously, particularly in the case of purines 1 ...

Now that ribose has been detected in two 4.5-billion-year-old meteorites (but 2-deoxyribose, the primary sugar in DNA, has not), scientists can make a stronger case that sugar from space bombarded ...
