Question: are oligos and primers the same thing?
Answer: A primer is a specific type of oligo. ... An oligonucleotide is a short chain of nucleic acids. A primer is an oligonucleotide of a certain length (20–25 nucleotides say) that is complementary to a target sequence in a DNA amplification procedure. All primers are oligonucleotides, but not all oligonucleotides are primers.
