Oligonucleotide synthesis is the chemical synthesis of relatively short fragments of nucleic acids with defined chemical structure (sequence). The technique is extremely useful in current laboratory practice because it provides a rapid and inexpensive access to custom-made oligonucleotides of the desired sequence. Whereas enzymes synthesize DNA and RNA only in a 5' to 3' direction, chemical oligonucleotide synthesis does not have this limitation, although it is most … WebT or F : More primers are expected to be used in the synthesis of the lagging strand than in the synthesis of the leading strand true In the polymerization of DNA, a phosphodiester … how many doors in a skyscraper
