Document Summary
Thus, biotechnology includes manipulations that do not involve dna technologies, such as the use of naturally occurring yeast to brew beer and bake bread and the use of bacteria to make cheese. The ancient dna studies described all began with. Pcr to amplify large amounts of dna for sequencing: remember that a clone is a line of genetically identical cells or individuals derived from a single ancestor. In basic research, a researcher might want to study a cloned gene to learn about its structure, including its dna sequence and sequences that regulate its expression. Dna sequences are used, for instance, for medical, forensic, agricultural, or commercial applications. Bacterial enzymes called restriction endonucleases form the basis of dna. Cloning: the key to dna cloning is the specific joining of two dna molecules from different sources, such as genomic dna fragment and a bacterial plasmid.
