A new paper, published today in Science, identifies widespread differences between DNA sequences and their corresponding RNA transcripts in human cells, and demonstrates that these differences result ...

Interestingly, this base substitution is not the only difference between DNA and RNA. A second major difference between the two substances is that RNA is made in a single-stranded, nonhelical form.

The more researchers examine RNA, the more surprises they continue to uncover. What have we learned about RNA structure and function ... that an RNA molecule and a DNA molecule could form a ...

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 ...

A History in Hybridization and Structure Alexander Rich and David Davies discover the double-stranded RNA helix and show that polyribo U and polyribo A hybridize spontaneously.6 Ben Hall and Sol ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA ... bonds form between the adjacent amino acids to finalise the structure.
