In this experiment six antibiotics will be tested to determine which is the most effective on gram-negative bacterium Escherichia Coli and gram-positive bacterium Bacillus Cereus. In previous class experiments‚ gram-staining was conducted to determine the qualities of gram-positive

Background: In Jane Horack’s article “Staphylococcus epidermidis”‚ S. epidermidis is described as “gram-positive cocci bacteria that are part of the normal flora on the skin and nasal passages.” The article goes on to say that the species was originally named Staphylococcus Albus by microbiologist Rosenback in 1884. When viewed under a microscope S. epidermidis will appear in chains‚ pairs‚ or grape-like clusters (Horak 1). Taxonomically‚ the species S. epidermidis falls in the genus Staphylococcus

BIO304: Forensic DNA Fingerprinting Lab DNA Fingerprinting‚ method of identification that compares fragments of DNA. It is sometimes called DNA typing. With the exception of identical twins‚ the complete DNA of each individual is unique. A DNA fingerprint is constructed by first extracting a DNA sample from body tissue or fluid such as hair‚ blood‚ or saliva. The sample is then segmented using enzymes‚ and the segments are arranged by size using a process called electrophoresis. The segments are

The introduction of the microscope as a tool for the biologist brought about a complete reappraisal of the micro- composition of biological tissues‚ organisms and cells. In the infancy of its application to organic materials‚ it was the implement of anatomists and histologists in particular‚ where previously unimagined structures in cells were revealed. More recent developments in biological specimen preparation have come from biochemists and physicists who have used the microscope to examine cells
