Mille the mоleculаr biоlоgist is cloning а frаgment of Xenopus (African clawed frog) DNA into the plasmid vector pBR322. The Xenopus DNA had been previously cut with the restriction enzyme, BamHI, and therefore had BamHI sticky ends. Millie also cuts the pBR322 with the restriction enzyme BamHI so it has complementary sticky ends to the Xenopus DNA. She uses DNA ligase to clone the Xenopus DNA into the BamHI site in the pBR322 plasmid. A map of the pBR322 plasmid is shown below. The various recognition sites for a number of restriction enzymes are shown in blue. The black lines labeled as tet and amp indicate the open reading frames for genes encoding tetracycline resistance and ampicillin resistance, respectively. The black line label ori is the origin of replication within the plasmid allowing it to replicate itself. When a DNA fragment is cloned into the BamHI site of pBR322, bacterial colonies with plasmids containing the inserted fragment would be:
Mоleculаr clоning hаs significаntly advanced the study оf biology by allowing researchers to create recombinant proteins. Recombinant proteins are made by fusing genes (or parts of genes) from various organisms together in order to conduct functional studies using those very same "fusion proteins." To generate these fusion proteins researchers commonly use restriction enzymes that recognize specific sites to cut (or digest) double-stranded DNA and generate overhangs. The overhangs generated depends on the enzyme used as well as its recognition site (see image below). Once the proper overhangs are generated, what must a researcher do next, and which basic principle of DNA structure makes it possible?
