![]() The 3′ carbon of one sugar is bonded to the 5′ phosphate of the adjacent sugar. The phosphate is attached to the 5′ carbon. What is the name of the linkage that connects phosphates to sugars in the sugar-phosphate backbone of DNA? Phosphodiester bonds Bases are held together by hydrogen bonds, and the DNA backbone is held together by phosphodiester bonds. What is the sugar-phosphate backbone of DNA held together by? The sugar phosphate backbones of the two chains run parallel to each other in opposite directions. Read More: What is a clinical microbiology laboratory? Are DNA sugar-phosphate backbones parallel?ĭNA molecules have two polynucleotide chains, held together in a ladderlike structure. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T). Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

It is this base sequence which forms the genetic code. This creates the twisting double helix structure of DNA.Īll cells store their genetic information in the base sequence of DNA. The two strands of DNA are antiparallel which means that one strand runs in a 5’ to 3’ direction and the other runs in a 3’ to 5’ direction. the 3' end (said as "3 prime end") at the deoxyribose end.the 5' end (said as "5 prime end") at the phosphate end.These strong bonds form a sugar-phosphate backbone. These basic units are linked together to form strands by strong bonds between the deoxyribose sugar of one nucleotide and the phosphate of the next nucleotide. They always pair up in a particular way, called complementary base pairing: There are chemical cross-links between the two strands in DNA, formed by pairs of bases held together by hydrogen bonds. The nucleotides are identical except for the base, which can be one of four bases:
