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 ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can ... These cytosine analogs exploit the ...

In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to form the iconic double helix structure. RNA is usually single-stranded but ...

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.
