Pentose sugars form part of the backbone of DNA and RNA strands, the sides of the ladder, to go back to the analogy from earlier. All of the nucleotide bases in nucleic acids are bound to the ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

Nucleic acids are the backbone of molecular biology research. As such, preservation of their integrity and purity is fundamental for genomic research. Low quality samples can lead to inconsistent ...

For instance, in a 1971 essay on the history of nucleic acid research ... discovery of the sugar-phosphate backbone of the DNA molecule was still years away. The large number of molecular groups ...
