Tick the correct statements: Remember: Tautomers are structural isomers that differ from each other based on the position of the proton(s) and their double bonds. ( ) The nitrogenous bases of nucleic acids, which contain heterocyclic and analogous nuclei, can adopt different tautomeric forms involving multiple H+ that are exchangeable depending on the medium. In DNA, spontaneous formation of smaller tautomers appears to contribute to mutagenic errors during DNA replication, while in RNA, they seem to be related to increased structural and functional diversity of enzymes and RNA aptamers (research this and confirm if it is false or real) ( ) in relation to the figure, anomer 1 has beta stereochemistry with respect to the C anomeric of the pentose, and is making an N-glycosidic bond ( ) in relation to the figure, anomer 1 has alpha stereochemistry with respect to the C anomeric of the pentose, and is making an N-glycosidic bond ( ) In general, in naturally occurring nucleosides, ribose or deoxyribose is linked to the bases through β-glycosidic bonds, being referred to as β-nucleosides.
