Blue white selection is a widely used method in screening recombinants in cloning. This is based on the gene product of lac z gene. The plasmid vectors contain this gene which produces β galactosidase enzyme. When a gene is inserted close to lac z gene‚ the reading frame will be distorted and the gene is inactivated. So the transformed cells will not produce this enzyme and are called competent cells. After the recombination‚ the bacterial cells are grown in a medium containing X gal (5-bromo-4-chloro-indolyl-β-D-galactopyranoside)

the origin of the phrase “once in a blue moon” and what a blue moon actually is. “Once in a blue moon” today means “very rarely‚” though it used to mean something that was absurd‚ right along the lines of “when pigs fly.” The first known recorded use of a form of the phrase is in an anti-clerical pamphlet published in 1528 by William Roy and Jeremy Barlowe.
