WebJan 21, 2024 · Together, the phosphate groups and sugars form the sugar-phosphate backbone, which makes up the outside of the DNA molecule. The nitrogenous bases point inwards, like the rungs of a ladder, and are joined together in base pairs. The base pairs of DNA are: Adenine-thymine Guanine-cytosine Base pairs in DNA WebDNA nucleotides assemble in chains linked by covalent bonds, which form between the deoxyribose sugar of one nucleotide and the phosphate group of the next. This arrangement makes an alternating chain of deoxyribose sugar and phosphate groups in the DNA polymer, a structure known as the sugar-phosphate backbone Chargaff's rules

WebJul 10, 2024 · Replication. New cells are continuously forming in the body through the process of cell division. For this to happen, the DNA in a dividing cell must be copied in a process known as replication. The complementary base pairing of the double helix provides a ready model for how genetic replication occurs. WebThere are four types of nitrogenous bases in DNA. Adenine (A) and guanine (G) are double-ringed purines, and cytosine (C) and thymine (T) are smaller, single-ringed pyrimidines.
