WebIn most cases, the primers of the Okazaki fragments can be easily replaced with DNA and the fragments connected to form an unbroken strand. When the replication fork reaches the end of the chromosome, however, there is (in many species, including humans) a short stretch of DNA that does not get covered by an Okazaki fragment—essentially, there's no … WebSome fast-growing bacteria such as pathogenic strains of E. coli can sicken and kill us; other bacteria in a subsurface environment can be used to immobilize chemical contaminants, preventing their movement through …

WebDNA cloning is the process of making many copies of a specific piece of DNA, such as a gene. The copies are often made in bacteria. In a typical cloning experiment, researchers first insert a piece of DNA, such as a gene, into a circular piece of DNA called a plasmid. This step uses restriction enzymes and DNA ligase and is called a ligation.
