Urine culture is a type of laboratory test which is utilized to estimate presence of bacteria and germs in the urine sample. It is done based on the complete urinalysis test.
The basic objective of this test is to study about the isolation and enumeration of bacteriophages from water sewage samples by using a double layer agar technique.
The concentration of RNA present is directly proportional to the absorbance of light carried out in a spectrophotometer. This Beer Lambert’s Law.
Estimation of DNA can be done by using various method like absorbance, agarose gel electrophoresis etc. Among all estimation using spectrophotometer is convenient
