Can any one write all possible(its 6 , I guess 🙄 ) combinations of primers in random priming?
No, Nobody will. Not because of the ‘homework policy’ of the forum, or because we don’t want to hel you but because you made a little mistake.
Random priming is made with hexanucleotides, or 6 nucleotide long primers with random nucleotide at each position. Hence there isn’t 6 combinations but 4^6 or 4096, and that is too much to type here 😉
