Beer’s Law Objective : We will explore an application of absorption spectroscopy using calibration curves and Beer’s Law. Use the “LAB : HOW TO…” link from the class website if you need help with how to use balance, Bunsen burner… and such. Introduction: You may write this information in your lab notebook for your own reference. It can’t be cut and pasted. Different solutions have different spectral properties. In this portion of the experiment those properties will be utilized to...

and Lab Exer n this experiment you will evaluate effect of UV light on bacterial growth. UV light affects growth by interfering with DNA, resulting in thymine dimer formation. The dimerization is confined within adjacent thymine residues on same strand (intrastrand ). These dimmer lesions have consequence on DNA functions including interference in DNA replication, transcription etc, so UV exposure of cells can lead to lethal effects for bacterial multiplications. This forms the basis for UV method to control bacterial...
