In DNA the 4 nitrogenous bases are Adenine, Guanine, Thymine, and Cytosine. In RNA Thymine is replaced by Uracil.
The four nitrogenous bases of DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases pair up in specific combinations (A with T and C with G) to form the double helix structure of DNA.
The structure of DNA contains nucleotides, which are made up of a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine). The nucleotides are arranged in a double helix formation, with the nitrogenous bases pairing specifically (A with T, C with G) to form the genetic code.
The four nitrogenous bases associated with DNA replication are adenine (A), thymine (T), guanine (G), and cytosine (C). They pair up in a specific manner - adenine pairs with thymine, and guanine pairs with cytosine - during the process of DNA replication to ensure accurate copying of genetic information.
The four parts of a DNA molecule are adenine, thymine, cytosine, and guanine, which are the four nitrogenous bases that make up the genetic code.
