,Reichsbehörden und Reichsbeamte,NAs or tRNAs, provide the 3′-hydroxyl (3′-OH) group needed by the DNA polymerase to elongate the DNA chain. Another mechanism is the use of the 3′-OH group provided by the DNA itself. A third type of primer for DNA synthesis is the hydroxyl group of a specific serine, threonine or tyrosine residue of a protein (.).

Direct Isolation of Specific Chromosomal Regions and Entire Genes by TAR Cloning, create a new YAC with alterations in specific regions (.). This approach can be used to generate YACs which, upon transfer into mammalian cells, will contribute to the functional analysis of the isolated region.

Nuclear Plasmids of , ,tion on which much of the progress in genetic engineering and molecular biology rests (.–.). Knowledge of plasmid biology - copy number control, compatibility, maintenance strategies, replication requirements - enabled the design of plasmid vectors with specific characteristics allowing otherwise impractical experiments.
