WebThe backbone is made intracellularly first, to hold the bases in the correct order. There are four bases found in DNA. These are known as A, T, G, and C. Their full names are adenine, … WebSolid lines represent strong bonds formed when electrons are shared by two atoms. Dotted lines represent a weak bond formed by an attraction between two atoms that do not share …

Web(B) A portion of the RNA strand viewed down the stack of bases from the 3 -end, with RNase H straddling the backbone and S74 engaging in two H-bonds to the amide nitrogen (thin lines; the position ... WebThe DNA backbone Nucleotides within a DNA strand are joined together by strong covalent bonds located in the DNA backbone. The chemical elements in the backbone are responsible for many of the physical properties of DNA, such as charge and strength. part time vs full time student osap

3.12: Nucleic Acids - The DNA Double Helix - Biology LibreTexts

WebThe main bonding in DNA which renders the double helix structure so stable is that of hydrogen bonds. As well as this there are hydrogen bonds between the bases and surrounding water molecules, and this combined with the even stronger phosphodiester bonds in the sugar phosphate backbone make DNA very stable. What are the steps of … WebThese strong bonds form a sugar-phosphate backbone. The ends of the DNA strand are called the 5' end (said as "5 prime end") at the phosphate end, and the 3' end at the … WebThe protein DNA ligase then fuses the sugar-phosphate groups of adjacent nucleotides to create the DNA backbone. These bonds are known as phosphodiester bonds. The only false statement concerns the identity of bonding between nitrogenous bases. Bases are held together by hydrogen bonds, and the DNA backbone is held together by phosphodiester … parttrappers
