Origin of the name Claire: Derived from the Latin clÄrus (bright, clear, famous). Clare is a common name throughout Europe and the British Isles, its popularity once due in part to the fame of St. Clare of Assisi (c. 1193 - 1253).The Italian nun who founded the order of the Poor Clares. From A World of Baby Names by Teresa Norman. named my daughter Clara Jane. I love her name. It has a classic wise feel to the name. It is not a popular name. I didn't want my daughter to be one of 10 kids with the same name in her classroom.
Restriction enzymes or to use their correct name, restriction endonucleases, are a type of enzyme which have the ability to cut molecules of DNA. They are often referred to as genetic scissors.
Restriction Enzymes Cut DNA Molecules at Specific Sequences. To clone specific DNA fragments in a plasmid vector, as just described, or in other vectors discussed in later sections, the fragments must be produced and then inserted into the vector DNA.As noted in the introduction, restriction enzymes and DNA ligases are utilized to produce such recombinant DNA molecules.he phenomenon of transformation permits plasmid vectors to be introduced into and expressed by E. coli cells. In order to be useful in DNA cloning, however, a plasmid vector must contain a selectable gene, most commonly a drug-resistance gene encoding an enzyme that inactivates a specific antibiotic.
