Question

define selectable markers and cloning sits

Answer 1

Due to the presence of the selective marker, the plasmid becomes useful for the cell. Under the selective conditions, only cells that contain plasmids with the appropriate selectable marker can survive. Commonly, genes that confer resistance to various antibiotics are used as selective markers in cloning vectors.

Answer 2

Define selectable markers and cloning. Sites

Answer =>

Selectable markers => it is an antibiotic resistant gene

Example => ampicillin resistant gene

=> cloning sites => for linking an alien DNA into the vector, there must be preferably single recognition sites for commonly used resistriction enzymes
