QUICK ANSWER: Nucleosides and nucleotides fundamentally differ in their chemical composition. The main difference between nucleosides and nucleotides is the presence of phosphate groups. Nucleosides ...

There are four bases: Adenine and Guanine (purines); Cytosine and Thymine (Pyrimidines). Purines have two carbon-nitrogen rings while pyrimidines have a single carbon-nitrogen ring. Thus, there are ...

The discovery of DNA ligase by the Gellert, Lehman, Richardson, and Hurwitz teams in 1967 was a breakthrough in molecular biology. These essential enzymes maintain genome integrity and play a vital ...

Abstract: Accurate identification of protein-nucleotide binding residues is essential for protein functional annotation and drug discovery. Advancements in computational methods for predicting binding ...

Chemists at the University of Illinois, Urbana-Champaign, have identified a deoxyribozyme that catalyzes amide hydrolysis, the first step toward making a DNA-based enzyme that can cleave proteins in ...

Here we explore the massive impact nucleic acid chemistry has had on the manufacture of synthetic DNA and RNA sequences whilst explaining the chemistry behind the chemical synthesis of DNA Nucleic ...

A recent study reported the discovery of a new mechanism that enables plants to fight against microbial infections. Earlier studies have shown that breaking down NAD + (nicotinamide adenine ...

More of the ingredients for life have been found in meteorites. Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA, scientists report ...
