in a structure resembling a ladder twisted into a spiral, called adouble helix.Each rung is made up of two chemical bases, callednucleotides,that are joined together by hydrogen bonds. There are four kinds of nucleotides in a DNA molecule: cytosine, guanine, adenine, and thymine—C, G, A...
Remember: "apples in the tree, cars in the garage." What is the structure of DNA bases? DNA is a long chain of smaller subunits called nucleotides. Each nucleotide has one nitrogenous base, a deoxyribose sugar, and a phosphate group. The outside (backbone) of DNA is composed of alternati...
DNAreplicatesby separating into two single strands, each of which serves as atemplatefor a new strand. The new strands are copied by the same principle of hydrogen-bond pairing between bases that exists in the double helix. Two new double-stranded molecules of DNA are produced, each containing...

7.1.4 Distinguish between unique or single-copy genes and highly repetitive sequences in nuclear DNA. Not all of the base sequences in DNA are translated. Highly repetitive base sequences are not translated. They consist of sequences of between 5 and 300 bases that may be repeated up to 10...
Figure 2: The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue). Although nucleotides derive their names from the nitrogenous bases they contain, they owe much of their struct...
There are two major classes of chemical probes of DNA structure: those that demonstrate no inherent base preference but are sensitive to DNA geometry, such as groove widths and chirality, and those that are base-specific, detecting bases in distorted regions of the helix. The former bind to DN...
