(a) Identify the selectable markers in the diagram of E. Coli vectior shown above .
( b) How is the coding squence of `alpha`- galactosidase consider a better markers than the ones identified by you in the diagram ? Explain.

Text Solution

Verified by Experts

Selectable markers are two antibiotic- resistant genes.
`"tet^(R)` = Tetracycline - resisttant gene and `amp^(R)` = Ampicllin - resistant gene.
`beta` - galactosidas marker provides of
`beta`- galactosiidase when a chromogenic substrate is added in the plating medium.
