netineya [11]

The blue-white screen refers to a procedure of screening that allows for the brisk and convenient determination of recombinant bacteria in vector-based molecular cloning experiments. In the process, the DNA of interest is ligated into a vector. The blue colonies constitute of self-relegated plasmids that are devoid of DNA inserts obstructing the lac Z gene.  

The white colonies contain bacteria that conduct plasmids, which possess the inserts of DNA fragments that obstruct the lac Z gene. Therefore, the researcher needs to sequence the plasmids of the white colonies prior to knowing which allele it constitutes.

Bacteria can make their own folic acid, which is required for nucleic acid synthesis, but humans cannot and instead have to inge
lidiya [134]

This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.

Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.

Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.

These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).
