Gene Cloning - CHERIC

7 Basic Steps of Gene Cloning 1)A fragment of DNA , containing the gene to be cloned, is inserted into a circular DNA molecule (vector) Æ"Recombinant DNA molecule" or "Chimera" 2)The vector acts as a vehicle that transports the gene into a host cell (usually, bacterium) Æ possibly other types of living cell.

(Obviously ketones and acids do not have these peaks). Diagram 12-9a, Carboxylic acids also have very strong O-H absorptions, seen as very broad peaks around 3000cm-1. Figure 12-10 (SLIDE) Resonance Lowering of Frequencies Just as conjugation (resonance) lowers the stretching frequency of C=C, the same is true for C=O double bonds.
