DNA fingerprinting, also called DNA typing, DNA profiling, genetic fingerprinting, genotyping, or identity testing, in genetics, method of isolating and identifying variable elements within the base-pair sequence of DNA (deoxyribonucleic acid). The RNA polymerase separats the two DNA strands, and adds RNA nucleotides in a 5'->3' direction, (following a template 3'->5'), following the same pairing rules as in DNA, except that a U is paired with a template A. To predict the sequence of a newly synthesized strand of DNA, based on the sequence of the original strand. Pairing Rules Every RNA nucleotide is designed to pair with only one other nucleotide. This is known as the "Base-Pair Rule". Start studying Worksheet on DNA, RNA Chapter 9/10. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule. stay in the nucleus and be copied by DNA. The specific pairing observed are A with T by two hydrogen bonds and G with C by three hydrogen bonds. nucleotide 17. Even though only a single nitrogen base is affected, as with point mutations, in this instance, the single base is either completely deleted or an extra one is inserted into the middle of the DNA sequence. Every DNA molecule has hundreds of thousands of base pairs, and each base pair has multiple bonds, so the rungs of the ladder are very strongly bonded together. A pairs with T C pairs with G In RNA, A pairs with U, instead of T. This twisting allows DNA to be more compact. I can show how this happens perfectly well by going back to a simpler diagram and not worrying about the structure of the bases.

Both are right handed. New bases are added, following the rules of base pairing (A with T and G with C). Nitrogenous Bases and Covalent Bonds. These "base pairing" rules are the key to understanding how DNA carries information and is copied into a new DNA strand (a cell must copy its DNA before it divides into two cells). DNA is made up of four similar chemicals—adenine, thymine, cytosine, and guanine—which are called bases and abbreviated as A, T, C, and G. In this arrangement, each base pair is of similar width, thus holding the sugar-phosphate backbones an equal distance apart along the DNA molecule.
