| 摘要 |
The present invention relates to a linker or population of linkers that include an oligonucleotide fixed portion and an oligonucleotide variable portion represented by formula (N)n, wherein N is A, C, G, T or U, or their derivatives, and n is an integer equal to or higher than 1. A linker-polynucleotide or a population of linker-polynucleotides of the invention may be constituted by said linker or population of linkers and a target first strand polynucleotide bound to said linker. The invention also encompasses a method of preparing said linker or population of linkers and a method of preparing a linker-polynucleotide using said linker or population of linkers. The linkers or polynucleotide-linkers of the invention can be used in a method of preparing a cDNA library.
