WebYour DNA structure is made up of four base pairs: adenine (A), cytosine (C), thymine (T), and guanine (G). The bases form pairs (base pairs); A with T and C with G. The base pairs connect with a sugar molecule and a phosphate molecule (making a nucleotide) that form a spiral staircase (double helix).
WebFeb 1, 2024 · Answer: Each nucleotide contains phosphate, sugar (of the deoxyribose type), and one of the four bases (Figure 8-4). When the phosphate group is not present, the base and the deoxyribose form a nucleoside rather than a nucleotide. The four bases are adenine, guanine, cytosine, and thymine. WebHaploid human genomes, which are contained in germ cells (the egg and sperm gamete cells created in the meiosis phase of sexual reproduction before fertilization) consist of 3,054,815,472 DNA base pairs (if X chromosome is used), [3] while female diploid genomes (found in somatic cells) have twice the DNA content.

DNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds. Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm). The pair of chains have …
