      How is a fragment of cDNA integrated into a plasmid although it does not have complementary extremities due to originating from restrictive endonucleasic digestion?

      Ive done a lab where we created a cDNA library I think but it was a long time ago and I dont remember the details so here is a link to something similar.

      If you used a PCR step with Taq polymerase, TA cloning is an option. Blunt end cloning is always possible, although the results are not very good.

      Thank you, that gave me the answer, which is:

      add linkers to all the cDNAs. These linkers are short oligonucleotide pieces of
      dsDNA that contain a restriction site within them. Add the enzyme DNA ligase,
      which will ligate the linkers to the ends of the cDNAs.
