This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule. DNA and RNA are composed of nucleotides that are linked to one another in a chain ...
DNA is found in nearly all living cells ... This means that one strand's sugar-phosphate chain runs in the 5' to 3' direction, whereas the other's runs in the 3' to 5' direction (Figure 4).
Combinations of these atoms form the sugar-phosphate backbone of the DNA -- the sides of the ladder, in other words. Other combinations of the atoms form the four bases: thymine (T), adenine (A ...
In the late nineteenth century, a German biochemist found the nucleic acids, long-chain ... that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA.
DNA is the molecular basis of heredity ... In this analogy nucleotides are the teeth of the zipper; the sugar-phosphate backbone is the fabric to which the teeth are attached.
The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
