The parts of a DNA nucleotide are a sugar, a phosphate group and a base. The sugar molecule used in DNA nucleotides is deoxyribose. The phosphate... Learn more about this topic: Nucleotide | Definition, Structure & Bonds from Chapter 24/ Lesson 6 ...
forms of life, alongside proteins, lipids, and complex carbohydrates (polysaccharides). As they are made up of smaller monomeric units called nucleotides, the two DNA strands are called polynucleotides. Each nucleotide is made up of a sugar called deoxyribose, a phosphate group, and one of four...
DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...
What is DNA made of? DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T)...

Therefore, the DNA nucleotide (Fig. 2.1 ) is composed of a 5-carbon sugar (called deoxyribose), a phosphate group, and a nitrogenous base (nitrogen-containing structure). Note the 5′-carbon (at the top) and the 3′-carbon (at the bottom) of the sugar. Fig.2.1 ......

Nicotinamide adenine dinucleotide (NAD) is a crucial coenzyme formed by the union of two nucleotides bonded covalently through their phosphate groups. It exists in cells in two forms: NAD+ (oxidized) and NADH (reduced). NAD participates in numerous redox reactions, facilitating the transfer of ele...
A nucleotide is a compound that has an aromatic base containing nitrogen, a sugar that is either ribose or deoxyribose, and a phosphate group. DNA and RNA are long strands of nucleotides with each nucleotide linked sequentially to the next and are polymers. A phosphate bond linkage is an impo...
