When you are delivering a speech, you must provide an oral citation for any words, information or ideas that are not your own. An oral citation is defined in Public Speaking, by Coopman and Lull (2009), as a âbrief reference to a source during a speechâ (p. 65).
In molecular biology, DNA ligase is a specific type of enzyme, a ligase, (EC 6.5.1.1) that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.n molecular biology, DNA ligase is a specific type of enzyme, a ligase, (EC 6.5.1.1) that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.
5. DNA ligases are enzymes specialized in tying the complementary DNA chains that form the DNA double helix. These enzymes are used in recombinant DNA technology to insert pieces of DNA cut by restriction enzymes into other DNA molecules undergoing the effect of the same endonucleases.1  Genetic Engineering Review-Image Diversity: DNA ligases..
