WebHomochirality is a common property of biomolecules such as DNA, RNA and proteins. In particular,{\ scshape d}-ribose and {\ scshape d}-deoxyribose enantiomers are found within living cells, while their mirror images, the {\ scshape l}-enantiomers, are not known to occur naturally even though the configurations are highly stable. WebRNA and DNA molecules have ribose and deoxyribose sugar respectively. Both are chiral, their chirality is due to D -ribose or deoxyribose sugar components. Previous Year Papers.

WebWe argue that, in addition to its coding function, the ability of DNA, unlike RNA, to adopt a B-DNA structure confers advantages both for information accessibility and for packaging. The information encoded by DNA is both digital - the precise base specifying, for example, amino acid sequences - and analogue. ... Most importantly, DNA chirality ... WebSince a racemic mixture of chiral nucleotides frustrates the enzymeless extension of RNA and DNA, the origin of homochirality must be intimately connected with the origin of life. Homochirality theories have elected to presume abiotic mechanisms for prebiotic enantiomer enrichment and post amplification, but none, so far, has been generally accepted.
