RNA
From Eterna Wiki
Ribonucleic acid, or RNA, is molecule present in all living organisms. Like DNA, RNA consists of a chain of simple building blocks called nucleotides.
The chemical properties of RNA allow this chain to fold back on itself, creating a diverse array of stable structures.
Comparison to DNA
Main article: Comparison of RNA and DNA RNA, like DNA. is composed of nucleotides. Each nucleotide consists of a sugar joined to a phosphate groupand a base. RNA differs from DNA in the identity of the sugar and one of the four bases. The sugar ribose present in RNA, while DNA contains the closely related sugar deoxyribose. Additionally, RNA incorporates the base uracil, while DNA makes use of its close relative, thymine.
