and a nitrogenous base. Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA, RNA is usually single-stranded.

In the case of DNA and RNA, these monomers are nucleotides. Nucleotides themselves are composed of three distinct parts: sugar, phosphate, and a nitrogenous base. Here's what each of those really ...

This process is called elongation. Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called ...

Three of these four nitrogenous bases—adenine, cytosine, and guanine—are also found in DNA. While DNA contains thymine, RNA includes uracil. RNA is key to the majority of biological processes ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...

RNA, or ribonucleic acid, is a essential biological molecule that plays a crucial role in various cellular processes. It is a polymeric molecule composed of nucleotides, each containing a ribose sugar ...

and several nitrogen-containing bases. Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA ...
