Rna

• RNA is ubiquitous family of large biological molecules that perform 
• Together with DNA,RNA compirses the nucleic acid 
• Like DNA,RNA is assembled as a chain of nucleotides 
• While many viruses encode their genetic information using an RNA

mutation

• In genetics, a mutation is a change of the nucleotide sequence 
• Mutations result from unrepaired damage to DNA and RNA
• Mutations play a part in both normal and abnormal biological 

Deoxyribose

• Deoxyribose, or more precisely 2-deoxyribose, is a monosaccharide with idealized formula
• Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose
• Since the pentose sugars arabinose and ribose only differ by the stereochemistry
• Several isomers exist with the formula H-(C=O)-(CH2)-(CHOH)3-H, but in deoxyribose

Thymine

• is one of the four nucleobases in the nucleic acid of DNA 
• As the name suggests, thymine may be derived by methylation of uracil 
• Thymine combined with deoxyribose creates the nucleoside
