Spread Plate Method: • In this method the mixed culture or microorganisms is not diluted in the melted agar medium (unlike the pour plate method); it is rather diluted in a series of tubes containing sterile liquid, usually, water or physiological saline. Project selection is the process of evaluating individual projects or groups of projects, and then choosing to implement some set of them so that the objectives of the parent organization will be achieved. METHODS OF CLONE IDENTIFICATION Nucleic acid hybridization: this method can be used to identify a particular recombinant clone if a DNA or RNA probe complementary to the desired gene is available Any two single stranded nucleic acid molecules have potential to form base pairs with one another with most pairs of molecules the resulting Anita Kumari presented on different assessment methods used in organizations.
