Abstract

This invention concerns self-avoiding molecular recognition systems (SAMRS), compositions that bind to natural DNA and RNA, but do not bind to compositions at sites that incorporate other SAMRS components, and processes dependent on them. Their utility is shown by discoveries that DNA polymerases accept these compositions as primers and templates, where standard triphosphates are added to primers containing SAMRS components, and added opposite to SAMRS components in the template. A critical mass of data are provided in 16 examples to provide first-generation heuristic rules to permit design of SAMRS sequences can be used as primers and templates that are accepted by DNA polymerases. The presently preferred primers are at least 12 nucleotide units in length, and more preferably between 15 and 30 nucleotides in length. Also preferred are chimeric primers that have standard nucleotides in their 5′-segments, and SAMRS nucleotides in their 3′-segments, and in multiplexed priming.
