A, C, G and T (and U) arenitrogenousbecause of the large amount of the element nitrogen they contain relative to their overall mass, and they arebasesbecause they are proton (hydrogen atom) acceptors and tend to carry a net positive electrical charge. These compounds do not need to be c...
What are the four nitrogen bases in DNA?DNA:Deoxyribonucleic acid (DNA) is a nucleic acid polymer composed of two polynucleotides held together by hydrogen bonds. Nucleic acids are composed of the nucleotide monomer. Nucleotides are made up of three parts: ...
Nitrogenous bases are organic molecules that contain nitrogen within their chemical structure. These bases are components of nucleotides, which make up DNA.Answer and Explanation: The four nitrogenous bases found in DNA are: Adenine, which pairs with thymine within the DNA double-helix. Thymine, ...
A nitrogenous base is an organic molecule that contains nitrogen and has the chemical properties of a base. There are four nitrogenous bases that occur in DNA molecules: cytosine, guanine, adenine, and thymine (abbreviated as C, G, A, and T). RNA molecules contain cytosine, guanine, and ad...
orRNA. RNA shares a similar structure to DNA, except it contains only one strand, rather than two — so it looks like just one half of a ladder. In addition, while RNA has three of the four nitrogen bases in common with DNA, it uses a base called uracil rather than thymine to pair...
Several types of bifunctional alkylating agents have been used for treatment of cancer diseases, such as nitrogen mustard analogs (1), platinum compounds (2), mitomycin C (3), and psoralens (4) (Scheme 6.1). Some modified nucleosides capable of cross-linking DNA have been used for studying ...

DNA：Structure DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what ...
DNase activity: Minimize DNase activity by quickly freezing plant tissues in liquid nitrogen upon collection and keeping them at low temperatures throughout the extraction process. Difficulty lysing the sample: To improve sample lysis efficiency, use mechanical disruption (e.g., homogenization or liquid...
There are two classes of nitrogen bases called purines (double-ringed structures) and pyrimidines (single-ringed structures). The four bases in DNA's alphabet are: adenine (A): a purine cytosine(C): a pyrimidine guanine (G): a purine thymine (T): a pyrimidine Watson and Crick discovered...
