No DNA tube- checks to make sure no unwanted DNA is contaminating any materials used. Each restriction enzyme is specific for a certain sequence of DNA. Place them in the foam tube rack. After electrophoresis, the only way that the DNA fragments will be visible is if they are stained. 4. Describe how a restriction enzyme can be used to determine if there is a single base-pair change between two otherwise identical pieces of DNA. 1. A gene is introduced for resistance to the antibiotic ampicillin into a bacterial strain that is killed by ampicillin. The scenarios were as follows, one plate with plasmid, one without and one plate with ampicillin and plasmid and one with ampicilin and without plasmid. Scientists can study genes and what they code for; also they can get bacteria to make products such as insulin for human use. Something is wrong with the ampicillin because the LB/amp-plasmid plate was a control that was used to test the viability of the ampicillin and all bacteria should have died. Confers resistance to the antibiotic penicillin. Genetic transformation occurs when a cell takes up (takes inside) and expresses a new piece of genetic material—DNA.

Print; Share; Edit; Delete; Report an issue; Live modes. RE's cut DNA at specific places called restriction sites. Bacterial transformation is a horizontal gene transfer process by which some bacteria take up foreign genetic material (naked DNA) from the environment. There was contamination by transformed bacteria or improper plating because the LB/amp-plasmid plate should have had no colonies. Natural competence is the genetic ability of a bacterium to receive environmental DNA under natural or in vitro conditions. Genetic transformation of the green florescent protein (GFP) gene into the bacterial cells of Escherichia Coli by use of the heat shock method of transformation. Two different DNA strands will be cleaved into different sized fragments. This new genetic information often provides the organism with a new trait which is identifiable after transformation. The negative charges on the phosphate molecules in the DNA are pulled toward the positive end of the gel. Even a single base change can prevent a restriction enzyme from cutting a DNA strand. In this experiment, bacteria will be transformed with a gene that codes for Green Fluorescent Protein (GFP). Add 100ul of the pGLO transformation cell mixture to the center of the agar surface of the corresponding LB agar and LB+AMP plates. How to calculate transformation efficiency.
