May 6, 2019. When nucleotides connect to form DNA or RNA, the phosphate of one nucleotide attaches via a phosphodiester bond to the 3-carbon of the.

Between the nitrogen-containing base and the phosphate group, which makes up the backbone of the DNA molecule, sits a sugar. It too has a ring form, composed of 5 atoms of carbon. This sugar is referred to as deoxyribose sugar, which indicates that as opposed to ribose sugar — used by RNA — it has lost a molecule of oxygen.

During replication, transcription, splicing, nick formation and other complex processes, the DNA in coiled form is unwinded and rewinded. Prokaryotic organisms like bacteria have coiled DNA in their cytoplasm present in a nucleoid region. They lack a membraned bound nucleus. The haploid human genomic DNA contains 3×10^9 nucleotides.

These form between parts of the molecules that have weak positive and negative charges. Because the hydrogen bonds are weak, they are able to break apart more easily than the rest of the DNA molecule. This is important when DNA reproduces itself and when it does its main work of controlling traits that determine what an organism looks like.
