Figure 1: A single nucleotide contains a nitrogenous base (red), a deoxyribose sugar molecule (gray), and a phosphate group attached to the 5' side of the sugar (indicated by light gray).

Nitrogenous Base: The nitrogenous base is a heterocyclic aromatic compound that contains nitrogen.There are two types of nitrogenous bases: purines (adenine [A] and guanine[G]) and pyrimidines ...

The nitrogenous bases stacked upon one another are spaced based on their van der Waals distance. Van der Waals distance is the distance at which two molecules are attracted to each other.

In addition to the five nitrogenous bases—adenine, guanine, cytosine, thymine and uracil—required for building DNA and RNA, ...

The nucleic acid adenosine triphosphate (ATP), made up of an adenine nitrogenous base, a 5-carbon ribose sugar, and three phosphate groups, is involved in generating energy for cellular processes.

How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As ...

Cytosine is one of the four main nitrogenous bases found in DNA and RNA, along with adenine (A), guanine (G), and thymine (T) or uracil (U). It is a pyrimidine derivative, meaning it has a single-ring ...

Researchers at The Scripps Research Institute (TSRI) claim to have created the first stable semisynthetic organism with extra bases added to its genetic code. The single-celled organism is also ...
