(Examples where this can be used are when you have sequences from related organisms or amino acid but not nucleotide sequence.)Ī technique that can be used if you need to amplify restriction fragments is to ligate short "adapter" sequences onto the ends of the restriction fragments.

If you don't know the exact sequence, but have some sequence information you can use "degenerate" primers, which are mixture of many similar (but non-identical) sequences.
This is typically done based on knowing the sequence you are trying to amplify.
PCR is usually used to amplify small quantities of DNA into a large enough amount to use for something else (e.g. Thus, there isn't enough "information" (sequence) present from knowing a restriction site to design a PCR primer. In contrast, primers are usually at least 18 nt long (often much longer) and so recognize a sequence that is on average at least 3 times longer. The recognition sequences for restriction enzymes are typically quite short (6 bp long is most usual). ligate it into a vector cut with the same REs).

If you use restriction enzymes (REs) then you usually already have enough DNA and can gel purify and use the cut fragment directly (e.g. Initial Name Necklace, Initial Letter Silver Pendant A to Z, Personalized Letter Necklace, Wife Gifts, Gifts For Mom, Birthday Gift for Her (1.4k) 33.74 44.99 (25 off) FREE shipping Sterling silver letter necklace, Tiny letter necklace, Letter M necklace, Dainty initial necklace gold, Small monogram necklace (3.4k) 46. You don't need to (and typically won't) cut the DNA before doing PCR.
