Deoxyribose is found in the cells of all living organisms, as it is a key component of deoxyribonucleic acid (DNA). DNA is made up of two chains of nucleotides bonded together. A nucleotide is formed when a 5-carbon sugar bonds to a phosphate group and a nitrogen-containing base. Nucleoti...
A double-stranded DNA molecule that has 22% guanine will have 1) 28% thymine 2) 22% cytosine 3) 44% adenine 4) 26% uracil 5) Both (1) and (2) are correct Nucleotides in DNA consist of which of the following? A) ...

We know that DNA is composed of nucleotides, each of which contains a nitrogen-containing base, a five-carbon sugar (deoxyribose), and a phosphate group. If the percentage of Guanine in one strand is 30%, what will be the percentage of cytosine in the ...
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 ......
Deoxyribose bound to a nitrogenous base is called anucleoside. When a phosphate group is added to deoxyribose at the carbon two spots away from where the base is attached, a complete nucleotide is formed. The peculiarities of the respective electrochemical charges on the various atoms in nucleotid...
DNA is a long string of these blocks or letters. Each nucleotide consists of a sugar (deoxyribose) bound on one side to a phosphate group and bound on the other side to a nitrogenous base. There are two classes of nitrogen bases called purines (double-ringed structures) and pyrimidines (...

There are four different DNA nucleotides — adenine (A), guanine (G), cytosine (C), and thymine (T) — each of which contains a phosphate, a deoxyribose sugar, and a nitrogenous base. Nucleotides are covalently linked to one another via the formation of a phosphodiester bond between the ...
At the most basic level, all DNA is composed of a series of smaller molecules callednucleotides. In turn, each nucleotide is itself made up of three primary components: a nitrogen-containing region known as anitrogenous base,a carbon-based sugar molecule calleddeoxyribose, and a phosphorus-contai...
