WebJul 31, 2024 · Many modifications of the oligonucleotide backbone have been used as antisense reagents or in synthetic siRNA for the control of gene expression. ... XNAs are nucleic acids in which the ribofuranose ring of DNA and RNA is replaced by five- or six-membered modified ribose molecules such as 1,5 anhydrohexitol nucleic acids (HNAs ... WebThe two strands go in opposite directions, with the nitrogen-containing bases facing inward to make the steps or rungs of the staircase and the sugar-phosphate backbone making up the outside walls of the helix. The hydrogen bonds between the nitrogen bases keep the two strands of DNA together and help keep the DNA molecule stable and whole. spaghetti bolognese with parmesan cheese

WebThe sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, … The backbone of the DNA strand is made from alternating phosphate and sugar groups. The sugar in DNA is 2-deoxyribose, which is a pentose (five-carbon) sugar. The sugars are joined by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings.
