Phosphodiester bonds ato
Did you know?
WebDNA ligase is a type of enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. It plays a role in repairing single-strand breaks in duplex DNA in living organisms, but some forms (such as DNA ligase IV) may specifically repair double-strand breaks (i.e. a break in both complementary ... WebA phosphoester bond is a bond between the phosphorous atom of a phosphate group and an oxygen atom. But considering the answer of electronpusher: Each nucleotide contains one phosphoester bond …
WebMar 26, 2024 · The bond between two phosphate groups is a phosphoanhydride bond which is supposed to be a high energy bond. According to this ATP has only two high energy bonds i.e., phosphoanhydride bond and no phosphodiester bond. So, the correct answer is "0" phosphodiester bond. Note: Adenosine triphosphate (ATP) is a nucleotide spent in cells … WebThe nucleotides combine with each other by covalent bonds known as phosphodiester bonds or linkages. The phosphate residue is attached to the hydroxyl group of the 5′ carbon of one sugar of one nucleotide and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, thereby forming a 5′-3′ phosphodiester bond.
Web2. The 3' hydroxyl group forms a bond to the phosphorus atom of the free nucleotide closest to the 5' oxygen atom. Meanwhile, the bond between the first phosphorus atom and the oxygen atom linking it to the next phosphate group breaks. 3. A new phosphodiester bond now joins the two nucleotides. A pyrophosphate group has been liberated. WebJan 10, 2024 · Bases are held together by hydrogen bonds, and the DNA backbone is held together by phosphodiester bonds. ] Question. Expert Answered.
