Oligonucleotides. Sample tubes containing oligo- nucleotides used in DNA research. Here, the oligonucleotides are used to create "antisense" molecules. Oligonucleotides are chains of nucleo- tides: purines and pyrimidines, which are the bases which form the genetic code of DNA. Oligo- nucleotides can be used to make "antisense" mole- cules, molecules which are genetically engineered to bind to a gene on the DNA. Oligonucleotides may also be used in PCR (Polymerase Chain Reaction) research to clone fragments of DNA.
